Influence of a Mixture of Protein Hydrolysate from Black Soldier Fly Larvae and Schizochytrium on Palatability, Plasma Biochemistry, and Antioxidative and Anti-Inflammatory Capacity in Cat Diets.

The objective of this research was to evaluate palatability, plasma biochemistry, antioxidative and anti-inflammatory capacity, and immune levels in cats by feeding supplementing inclusion of different levels of a mixture of protein hydrolysate from black soldier fly larvae and schizochytrium (BSFPs) in diets. In the feed experiment, a total of 24 adult cats (12 females and 12 males; BW: 3.02 ± 0.06 kg) were randomly divided into four groups: (1) diet with chicken and fish meal as primary protein resource (CON); (2) diet with 5% BSFPs replacing chicken meal, fish meal, chicken oil, and fish oil (5% BSFPs); (3) 10% BSFPs; and (4) 15% BSFPs. The body weight and feed intake were recorded, and a blood sample was collected for analysis. In the palatability experiment, three diets containing 5%, 10%, and 15% BSFPs were evaluated by comparing with CON. These results suggested that different levels of BSFPs could improve palatability in cat diets by enhancing the first sniff, the first bite, and feed intake (p < 0.05). However, no significant influence existed in body weight and average daily feed intake (p > 0.05). In comparison to the CON group, 5% and 15% BSFPs significantly increased the total protein content, and all treatment groups decreased the triglyceride content and enhanced the calcium concentration in plasma; in addition, the activity of aspartate aminotransferase and alanine aminotransferase and the content of creatinine and urea nitrogen were significantly reduced by the supplementation inclusion of BSFPs in the diets (p < 0.05). The enzyme activity of glutathione peroxidase was dramatically enhanced by the supplementation of 10% and 15% BSFPs in diets compared with the CON diet, and the activity of superoxide dismutase was increased and the malondialdehyde concentration was remarkably reduced in all three treatments (p < 0.05). Compared with the CON group, different levels of BSFPs in the diets significantly increased the immunoglobulin A content in plasma; similarly, the immunoglobulin G concentration was significantly enhanced by the supplementation of 10% and 15% BSFPs in the diets (p < 0.05). Furthermore, the interleukin-1ß content was significantly reduced in the inclusion of 10% and 15% BSFPs in the diets, and 15% BSFPs remarkably decreased the content of interleukin-8 in plasma compared with the CON diet (p < 0.05). To sum up, the supplementation of different levels of BSFPs exhibited a positive effect on palatability and enhanced the antioxidant, anti-inflammatory, and immune capacity. Particularly, the addition levels of 10% and 15% BSFPs were more effective in antioxidation, anti-inflammation, and immunity.

A Review of Pet Food Recalls from 2003 Through 2022.

This is a review of U.S. Food and Drug Administration (FDA) recalls of products that are for dogs and cats which took place from 2003 through 2022. It includes recalls for pet foods (food, treats, and chews), ingredients, supplements (vitamins and minerals), and drugs. There were 3,691 recalls during this period: 51% were Class I, 35% were Class II, and 14% were Class III. Food items and ingredients accounted for the majority or 68%, drugs for 27%, and supplements (vitamins and minerals) accounted for 5% of these recalls. Recalls that could be associated with dogs only accounted for 42%, with cats only 18%, and with multiple species 40%. The primary reasons for the recalls were biological contamination at 35%, chemical contamination at 32%, and cGMP violations at 8%. Almost 25% of the total recalls in the past 20 years were due to a melamine incident in 2007/2008 (73% of those were Class I). Salmonella recalls for the 20 years accounted for 23% of the total recalls (94 % of those were Class I). Although the recalls for vitamins and minerals accounted for only 5.6% percent of the total, 70% of those were Class I and 30% Class II. Pet food is a complex part of the processed food industry, and the processing of pet food is subject to at least 40 different federal regulations. To avoid recalls and be successful, pet food manufacturers need a robust food safety culture to meet all of these requirements to produce a safe product. In contrast, the melamine contamination (an adulteration event) in 2007/2008 which resulted in animal deaths and recalls is a prime example of the need for an effective and robust supplier approval program in order to avoid fraudulent suppliers in the future.

In-silico and in-vitro screening of Asiatic acid and Asiaticoside A against Cathepsin S enzyme.

BACKGROUND: Atherosclerosis is a form of cardiovascular disease that affects the endothelium of the blood vessel. Series of events are involved in the pathophysiology of this disease which includes the breaking down of the connective tissue elastin and collagen responsible for the tensile strength of the arterial wall by proteolytic enzyme. One of these enzymes called Cathepsin S (CatS) is upregulated in the progression of the disease and its inhibition has been proposed to be a promising pharmacological target to improve the prognosis of the disease condition. Asiatic acid and asiaticoside A are both pentacyclic triterpenoids isolated from Centella asiatica. Their use in treating various cardiovascular diseases has been reported. METHODS: In this study through in silico and in vitro methods, the pharmacokinetic properties, residue interaction, and inhibitory activities of these compounds were checked against the CatS enzyme. The SwissADME online package and the ToxTree 3.01 version of the offline software were used to determine the physicochemical properties of the compounds. RESULT: Asiatic acid reported no violation of the Lipinski rule while asiaticoside A violated the rule with regards to its molecular structure and size. The molecular docking was done using Molecular Operating Environment (MOE) and the S-score of - 7.25988, - 7.08466, and - 4.147913 Kcal/mol were recorded for LY300328, asiaticoside A, and asiatic acid respectively. Asiaticoside A has a docking score value (- 7.08466Kcal/mol) close to the co-crystallize compound. Apart from the close docking score, the amino acid residue glycine69 and asparagine163 both interact with the co-crystallized compound and asiaticoside A. The in vitro result clearly shows the inhibitory effect of asiaticoside and asiatic acid. Asiaticoside A has an inhibitory value of about 40% and asiatic acid has an inhibitory value of about 20%. CONCLUSION: This clearly shows that asiaticoside will be a better drug candidate than asiatic acid in inhibiting the CatS enzyme for the purpose of improving the outcome of atherosclerosis. However, certain modifications need to be made to the structural make-up of asiaticoside A to improve its pharmacokinetics properties.

Ascophyllum nodosum as a nutrient supporting oral health in dogs and cats: a review.

Home dental care is a key element of periodontal therapy in veterinary patients. Among many strategies of passive home dental care there is a supplementation of animal diet with seaweed Ascophyllum nodosum which have been shown to reduce both calculus and plaque accumulation after oral administration in both dogs and cats. Ascophyllum nodosum contains numerous biologically active ingredients, including micro-elements, vitamins, and several other compounds, however the exact mechanism of its beneficial action remains unclear. The very first metabolomic data suggest that it could change the composition of dog saliva. Several products containing Ascophyllum nodosum had been assessed clinically according to standards and requirements provided by the Veterinary Oral Health Council. The conducted clinical trials in dogs and cats revealed that Ascophyllum nodosum exerts the strongest preventive action as powder, followed by dental bites and dry pet food. The data concerning its curative action are limited to one study in cats in which no beneficial action has been observed. Based on available clinical data it is recommended to administer Ascophyllum nodosum to dogs and cats after oral cavity prophylactic procedure to reduce the recurrence of plaque and calculus formation.

Dietary omega-3 fatty acids in the management of feline periodontal disease: What is the evidence?

Periodontal disease is an oral disorder with high prevalence in cats from 2 years of age, resulting from an inflammatory response against bacterial plaque. Treatment depends on the stage of the disease and may include dental scaling, local application of perioceutics, tissue regeneration and/or even tooth extraction and periodontal surgery. As multimodal therapy is often required, new strategies have been developed to improve the therapeutic response in these patients. Adjuvant use of omega-3 fatty acids has been reported in humans with periodontal disease, but the current evidence of its effect in companion animals, especially cats, is still considered to be scarce and conflicting. This review describes the state of the art regarding feline periodontal disease and seeks to clarify the potential effect of omega-3 fatty acids on its clinical management in light of the evidence available in the current literature.

Prevalence of multidrug-resistant coagulase-positive staphylococci in canine and feline dermatological patients over a 10-year period: a retrospective study.

Coagulase-positive staphylococci (CPS) are common cutaneous pathogens often requiring multiple courses of antibiotics, which may facilitate selection for methicillin-resistant (MR) and/or multidrug-resistant (MDR) strains. To determine the prevalence of canine and feline MR/MDR CPS associated with skin diseases, medical records were retrospectively searched from April 2010 to April 2020. Pets with at least one positive culture for CPS were selected. Age, sex, antimicrobial sensitivity, previous history of antimicrobial/immunomodulatory medications and methicillin resistance/multidrug resistance status were recorded. Staphylococcus pseudintermedius (SP) (575/748) and Staphylococcus schleiferi (SS) (159/748) in dogs, and Staphylococcus aureus (12/22) in cats, were the most common CPS isolated. Three hundred and twenty-three out of 575 isolates were MR-SP (56.2 %), 304/575 were MDR-SP (52.8 %), 100/159 were MR-SS (62.9 %) and 71/159 were MDR-SS (44.6 %). A trend analysis showed a significant increase of resistance to oxacillin and chloramphenicol for S. pseudintermedius (r=0.86, 0.8; P=0.0007, 0.0034, respectively). Major risk factors for MDR-SP included oxacillin resistance (OR: 3; 95 % CI: 1.4-6.5; P=0.0044), positivity for PBP2a (OR: 2.3; 95 % CI: 1-5; P=0.031) and use of antibiotics in the previous year (OR: 2.8; 95 % CI: 1.3-5.8; P=0.0071). Oxacillin resistance was identified as a major risk factor for MDR-SS (OR: 8.8; 95 % CI: 3.6-21.1; P<0.0001). These results confirmed the widespread presence of MR/MDR CPS in referred dermatological patients. Judicious antibiotic use, surveillance for MR/MDR infections and consideration of alternative therapies are crucial in mitigating the development of resistant strains.

Nutritional secondary hyperparathyroidism in a kitten, supported by immunoenzymatic measurement of feline intact parathyroid hormone.

A 6-mo-old, intact male, domestic shorthair cat was referred with a history of poor growth, reluctance to move, and deformation of the nasal profile. The kitten had been fed a diet composed almost exclusively of a complementary pet food and tuna, which was similar to an all-meat diet. We detected osteopenia and hypocalcemia associated with severe parathyroid hormone (PTH) and calcitriol increases; we measured PTH concentrations with an immunoenzymatic method that has been validated in cats. Dietary correction, consisting of a complete and balanced wet pet food formulated for growth, resulted in normalization of calcium and PTH concentrations within 2 mo.

Uso da homeopatia em animais oncológicos / Use of homeopathy in animals oncological

O câncer é um dos maiores problemas de saúde nos animais e uma das principais causas de morte em cães e gatos, tornando-se cada vez mais frequente na clínica médica, principalmente em pacientes geriátricos. Tratamentos com menos efeitos adversos, objetivando melhor qualidade de vida e bem-estar físico e emocional, fazem com que o atendimento integrativo e complementar ao câncer cresça a cada dia, incluindo a homeopatia. Na oncologia, a homeopatia é usada de forma única ou complementar aos tratamentos convencionais, com inúmeros benefícios aos animais, contribuindo para redução dos efeitos colaterais dos antineoplásicos e dos sinais clínicos da doença. Além disso é um método de tratamento com pouco ou nenhum efeito colateral, seguro e eficaz, não é invasivo, a forma de administração é simples, altamente palatável, aumentando sua aceitação. Tem boa relação custo-benefício e a falta de um diagnóstico preciso, não representa um impedimento para iniciar o tratamento com os medicamentos homeopáticos. Assim, o objetivo deste trabalho é explorar as evidências através de análise bibliográfica, dos benefícios da homeopatia na oncologia veterinária.

Cancer is one of the biggest health problems in animals and one of the main causes of death in dogs and cats, becoming increasingly common in clinical medicine, especially in geriatric patients. Treatments with fewer adverse effects, aiming at better quality of life and physical and emotional well-being, make integrative and complementary care for cancer grow every day, including homeopathy. In oncology, homeopathy is used alone or as a complement to traditional treatments, with many benefits to animals, hoping to reduce the side effects of antineoplastic drugs and the clinical signs of the disease. In addition, it is a treatment method with little or no side effects, safe and effective, it is not invasive, the form of administration is simple, highly palatable, increasing its acceptance. It has a good cost-benefit ratio and the lack of an accurate diagnosis does not represent an impediment to starting treatment with homeopathic medicines. Thus, the objective of this work is to explore, as proven through bibliographical analysis, the benefits of homeopathy in veterinary oncology.

The effects of 105 biological, socioeconomic, behavioral, and environmental factors on the risk of SARS-CoV-2 infection and a severe course of COVID-19: a prospective, explorative cohort study.

The confirmed number of SARS-CoV-2 infections up to 18 October 2022 is 626 million worldwide, but information about factors affecting the probability of infection or a severe course of COVID-19 remains insufficient and often speculative. Only a small number of factors have been rigorously examined, mostly by retrospective or cross-sectional studies.We ran a preregistered study on 5164 Internet users who shared information with us about their exposure to 105 risk factors and reported being COVID-19 negative before the beginning of the fourth wave of COVID-19 in the Czech Republic. After the fourth wave, in which 709 (13.7%) of participants were infected, we used a partial Kendall test controlled for sex, age, and urbanization to compare the risk of infection and a severe course of the disease in subjects who initially did and did not report exposure to particular risk factors.After the correction for multiple tests, we identified 13 factors - including male sex, lower age, blood group B, and larger household size - that increased the risk of infection and 16 factors - including mask-wearing, borreliosis in the past, use of vitamin D supplements, or rooibos drinking - that decreased it. We also identified 23 factors that increased the risk of a severe course of COVID-19 and 12 factors that decreased the risk.This preregistered longitudinal study is of explorative nature. Therefore, although the observed effects were strong and remained highly significant even after correction for multiple tests, it will be necessary to confirm their existence in future independent studies.

Effects of isoflavone supplementation on endometrial thickness, endometrial hyperplasia, and cancer in ovariectomized cats.

Ovariectomy is identified as a standard treatment in different European countries. Isoflavones, as nonsteroidal compounds in plants, are common constituents of soy and soy products. Some available cat diets contain different concentrations of soy products. This study aimed to examine the effects of isoflavone supplementation on endometrial hyperplasia and endometrial thickness in ovariectomized cats. Fifteen neutered adult cats were divided into control, estradiol, and isoflavone groups (five cats per group). Subcutaneous injection of estradiol (0.5 µg) in sesame oil (100 µL) was done for 30 days in estradiol-treated cats. Isoflavone-treated cats ingested a single oral tablet of soy extract for 30 days, while the controls received subcutaneous injections of the vehicle and oral placebo for 30 days. Histopathological findings of hematoxylin and eosin-stained sections revealed a significant difference between the estradiol group and other groups in terms of hyperplastic epithelium and simple hyperplasia. Thickness of myometrium was greater in the estradiol group compared to the isoflavone and control groups. Higher concentrations of estrogen can affect the endometrium and myometrium, while 30-day ingestion of isoflavone didn't have any uterine effect.

Cantharis dissolves calculus in the ureter of a kitten: case repor

Urolithiasis is a disease thatcan occur alone or together, obstruct the urinary flow, and even progress to the animal's death. Objective:The present study is to report the dissolution of calculus in the ureter in a kitten. Methodology: a feline, SRD, male, started at 3 months old with the signs of vomiting, constipation,and hematuria, presenting leukocytosis and increased serum urea. Two abdominal ultrasounds were performed 30 days apart and the third at 3 months. Results:Inthe first ultrasound there was hydronephrosis in the right kidney and dilation of the ureter and microlithiasis in the urinary bladder. The animalhad already been treated with antibiotic therapy and did not improve. Given these characteristics, Cantharis Vesicatoria30cH was administered, there was no more hematuria and when the drug was discontinued, the symptom returned. After 30 days of startinghomeopathic treatment, we repeated the ultrasound which showed 2 kidney stones, and a urinary bladder with cystitis associated with sandy lithiasis. BerberisVulgaris30cH was then administered for 15 days, after which both drugs were discontinued and theanimal remained asymptomatic. After 3 months the ultrasound was repeated which showed 2 kidney stones, Causticum6cH was inserted for 14 days to dissolvekidney stones, thus preventing the return of the initial symptoms. Conclusion:the treatment was beneficial for the patient, who was asymptomatic after the use of Causticum.Considering the natural history of the disease in cats and the high chance of recurrence of the disease, the recommendation was to monitor the organs through an annual ultrasound examination, in addition to encouraging water intake.

Feline Injection-Site Sarcoma Complete Remission After Treatment with Isopathic medicine: a case repor

Feline injection-site sarcomas (FISS) were described for the first time in 1991. They are neoplasms of mesenchymal origin that appear in body regions routinely used for the application of vaccines or other injections [1]. Those are very aggressive tumours that relapse and have a high rate of mortality. The tumour can appear between 3 months and 3 years after the injection, but in some cases, it can happen after 15 years of the vaccineor otherinjections. Isopathy is one approach of homeopathy, in which the biological agent thatcausesa disease are prepared in high dilution to treat the same disease. This case report is about a 13-year-old mix breed spay cat. In September 2019 it received the vaccine Rabsin® (Boehringer Ingelheim) and 4 months later the owner noticed a lump at the injection area. One year later (September 2020) the lump start growing rapidly and on January 12th, 2021,started the appointments.The other veterinarians recommend euthanasia since the tumour was very bigand the catwasnot mild, was losing weightand appetite. The owner wanted to try another treatment before euthanasia since the cat was still active, interacting with the other cat and the people at the house.The lump was located on her back, in the end of the right ribcage, and it was around 7cm of diameter. It wasfirmandattachedto the muscles. AnIsopathy medicine with the same vaccinewas prepared, being the isotherapic 12CH administered 5 drops BID.Beside the isopathyvitaminsof Bcomplex and Omega 3were prescribed.The cat was seen every15 days andcontact telephonically was kept as well. The treatment started on January 19th, 2021. On January 21st, 2021,all the tumour was ulcerated and looser. On February 2nd,2021 the potencywas changedto 14CH, 5 drops, BID. On February 4ththe tumour felt away and was sent for histopathological study. On February 20th, 2021,the result described it as a Fibrosarcoma grade II. The ulcer that appeared after the tumour felt away became a big wound and the ownerstarted cleaning itwith propolis and lavender oleateeveryday anditwas controlledonce a week. OnMarch31st, 2021,the catwas eating well,strong, not mild,didnot allowedit to be cleaned. The woundseems to be more superficial,largerand it appears thata small lump was growing again.Isotherapic 15CH, 5 drops once a weekwas indicated.On April4th, 2021,the cat waseating well, good general conditionand the small lump that was growing wasshrinkingand the wound becoming more superficial. OnApril 9th,2021the cat seems painful, not eating well, constipated. Isopathy was suspended and started with Meloxican0,1mg/kg SID for 3 days.Was indicatedNatrum muriaticum30CH, 5 drops every hour, total 3 treatments and then once a day. On April 13th, 2021,the cat was better, defecate. But since April 9ththe cat could never be stable again. It has ups and downs and was treated withdifferent homeopathic remedies (Natrum muriaticum30Ch, Silicea200CHand Silicea1000CH, Staphisagria 200CH)until June 8th, 2021,when it was euthanised.No necropsy was done. The question was,what happenedwith the catsince itwas getting better?The following aphorisms could explain it:§156 "...The restoration, however, leads to the goal of the cure, if it is not preventedby strange medicinal influence, by errors in the lifestyle or by passions." And§10"With no vital powerthe material organism is not capable of any sensation, function or self-preservation..."[2].The informed consent formwas obtained from the owner of the cat.

Dietary calcium to phosphorus ratio affects postprandial phosphorus concentrations in feline plasma.

The impact of dietary phosphorus on chronic renal disease in cats, humans and other species is receiving increasing attention. As Ca and P metabolism are linked, the ratio of Ca:P is an important factor for consideration when formulating diets for cats and other animals. Here, we describe a fully randomised crossover study including twenty-four healthy, neutered adult cats, investigating postprandial responses in plasma P, ionised Ca and parathyroid hormone (PTH) following one meal (50 % of individual metabolic energy requirement) of each of six experimental diets. Diets were formulated to provide P at either 0·75 or 1·5 g/1000 kcal (4184 kJ) from the soluble phosphorus salt sodium tripolyphosphate (STPP, Na5P3O10), variable levels of organic Ca and P sources, and an intended total Ca:P of about 1·0, 1·5 or 2·0. For each experimental diet, baseline fasted blood samples were collected prior to the meal, and serial blood samples collected hourly for 6 h thereafter. For all diets, a significant increase from baseline was observed at 120 min in plasma PTH (P < 0·001). The diet containing the highest STPP inclusion level and lowest Ca:P induced the highest peaks in postprandial plasma P and PTH levels (1·8 mmol/l and 27·2 pg/ml, respectively), and the longest duration of concentrations raised above baseline were observed at 3 h for P and 6 h for PTH. Data indicate that Ca:P modulates postprandial plasma P and PTH. Therefore, when formulating diets containing soluble P salts for cats, increasing the Ca:P ratio should be considered.

Spinal Locomotion in Cats Following Spinal Cord Injury: A Prospective Study.

This article aimed to evaluate the safety and efficacy of intensive neurorehabilitation in paraplegic cats, with no deep pain perception (grade 0 on the modified Frankel scale), with more than three months of injury. Nine cats, admitted to the Arrábida Veterinary Hospital/Arrábida Animal Rehabilitation Center (CRAA), were subjected to a 12-week intensive functional neurorehabilitation protocol, based on ground and underwater treadmill locomotor training, electrostimulation, and kinesiotherapy exercises, aiming to obtain a faster recovery to ambulation and a modulated locomotor pattern of flexion/extension. Of the nine cats that were admitted in this study, 56% (n = 5) recovered from ambulation, 44% of which (4/9) did so through functional spinal locomotion by reflexes, while one achieved this through the recovery of deep pain perception. These results suggest that intensive neurorehabilitation can play an important role in ambulation recovery, allowing for a better quality of life and well-being, which may lead to a reduction in the number of euthanasia procedures performed on paraplegic animals.

Therapeutic Effect of EPA/DHA Supplementation in Neoplastic and Non-neoplastic Companion Animal Diseases: A Systematic Review.

BACKGROUND/AIM: The aim of this study is to identify and describe randomized controlled studies evaluating the therapeutic effect of EPA and DHA supplementation in companion animal diseases. MATERIALS AND METHODS: A systematic search was conducted in PubMed database and the information collected was summarized and evaluated according to the risk of bias, using the revised Cochrane tool (RoB2). RESULTS: Twenty-three studies were eligible for inclusion: twenty performed in dogs and three in cats. A therapeutic benefit was found in canine allergic dermatitis, haircoat disorder, keratoconjunctivitis sicca, valvular disease, and canine and feline osteoarthritis. Dogs diagnosed with chronic heart failure and lymphoma and cats with allergic dermatitis also seem to benefit from supplementation with omega-3 fatty acids, but studies with improved methodological quality are needed to strengthen this evidence. CONCLUSION: EPA and DHA supplementation has proven benefits in the adjuvant treatment of various neoplastic and non-neoplastic diseases in dogs and cats.

Relationship between a plant-based 'vegan' pet food and clinical manifestation of multiple nutrient deficiencies in two cats.

A topical subject in human nutrition is the steadily growing number of people choosing to limit or completely avoid all animal-derived food products either for moral dilemma, health concerns or both. To meet people's will of applying their dietary choices to their domestic animals, the pet food industry answered by launching on the market some plant-based diets. This leads to concerns about whether these diets are adequately formulated to satisfy the target species nutritional requirements, especially for cats which are still considered strict carnivores. This case report follows a 2-year-old male neutered Main Coon and a 1-year-old female spayed Domestic Shorthair cat, presented to the nutrition service of the University of Toulouse, France. Reason for consultation was lethargy with in anamnesis a recent dietary transition to a plant-based pet food. Dysorexia, lethargy and muscle waste were present at first consultation. Progressive weight loss developed during follow-ups. A macrocytic, non-regenerative anaemia with serum folates below reference were the main clinical features. Analysis of pet food showed multiple nutrients below minimum recommendation at the average daily intake of both cats. Folic acid supplementation improved dysorexia, and subsequent reintroduction of animal-derived ingredients in the diet restored appetite, weight and a normal mentation in both cases.

Towards establishing no observed adverse effect levels (NOAEL) for different sources of dietary phosphorus in feline adult diets: results from a 7-month feeding study.

High dietary phosphorus (P), particularly soluble salts, may contribute to chronic kidney disease development in cats. The aim of the present study was to assess the safety of P supplied at 1 g/1000 kcal (4184kJ) from a highly soluble P salt in P-rich dry format feline diets. Seventy-five healthy adult cats (n 25/group) were fed either a low P control (1·4 g/1000 kcal [4184kJ]; Ca:P ratio 0·97) or one of two test diets with 4 g/1000 kcal (4184 kJ); Ca:P 1·04 or 5 g/1000 kcal (4184kJ); Ca:P 1·27, both incorporating 1 g/1000 kcal (4184 kJ) sodium tripolyphosphate (STPP) - for a period of 30 weeks in a randomised parallel-group study. Health markers in blood and urine, glomerular filtration rate, renal ultrasound and bone density were assessed at baseline and at regular time points. At the end of the test period, responses following transition to a commercial diet (total P - 2·34 g/1000 kcal [4184kJ], Ca:P 1·3) for a 4-week washout period were also assessed. No adverse effects on general, kidney or bone (skeletal) function and health were observed. P and Ca balance, some serum biochemistry parameters and regulatory hormones were increased in cats fed test diets from week 2 onwards (P ≤ 0·05). Data from the washout period suggest that increased serum creatinine and urea values observed in the two test diet groups were influenced by dietary differences during the test period, and not indicative of changes in renal function. The present data suggest no observed adverse effect level for feline diets containing 1 g P/1000 kcal (4184 kJ) from STPP and total P level of up to 5 g/1000 kcal (4184 kJ) when fed for 30 weeks.

Evaluation of Mercury Contamination in Iranian Wild Cats Through Hair Analysis.

Due to its environmental persistence and bioaccumulative properties, mercury is considered highly toxic to humans, ecosystems, and wildlife. The present study aimed to investigate the total mercury (Hg) concentrations in hair samples of 40 wild cats belonging to eight different species collected from various provinces of Iran and to characterize their risk of Hg exposure. Total Hg levels in Iranian wild cats ranged from 62 to 3670 ng/g dw hair, with a median value of 488 ng/g dw hair. The lowest median Hg concentration was found in west Iran (251 ng/g dw hair), while the highest median level was measured in the north-east of the country (736 ng/g dw hair), likely related to its past use in agriculture and potential contamination of industrial effluents. The overall contamination of Iranian wild cats with mercury can be considered generally low, but 20% of the samples reached levels above 1100 ng/g dw hair, set as indicative of an environmental Hg concern according to the U.S. Fish and Wildlife Service. Our data are comparable with other investigations on wildlife worldwide, confirming the suitability of museum collection specimens to assess the environmental levels of Hg. We showed that, while diet and habitat can influence the mercury accumulation in wild cats, complementary factors, such as age, size, and interspecific metabolic differences, should be considered as well in future investigations.

DHA from microalgae Schizochytrium spp. (Thraustochytriaceae) modifies the inflammatory response and gonadal lipid profile in domestic cats.

The present study aimed to evaluate the inflammatory response, oxidative status and fatty acid deposition in reproductive tissues of cats supplemented with the dried microalgae Schizochytrium spp. (Thraustochytriaceae) as a DHA source. Thirty-seven cats (males, n 21; females, n 16; 11·5 (sd 0·5) months of age) were divided by sex into five groups. Treatment diets contained algae biomass at 4·0, 8·0, 12·0 or 16·0 g/kg replacing poultry fat (n-6 source). Cats were fed the respective diet for 62 d and neutered on day 58. Blood samples were collected at the beginning of the experiment (day 1), before neutering (day 58) and 4 d after surgery (day 62) for analysis of inflammation and oxidative markers. Acute-phase protein levels were altered (P < 0·01) in the postoperative period, without any treatment effect (P > 0·05). PGE2 concentrations after surgery were reduced linearly (R2 0·8706; P = 0·002) with microalgal inclusion. Blood platelet count was reduced (P = 0·001) after the surgery regardless treatment, but it was higher in the DHA group compared with control (P < 0·001). The DHA deposition (testicles, R2 0·846; ovaries, R2 0·869) and the n-6:n-3 ratio (testicles, R2 0·859; ovaries, R2 0·955) in gonads had a pattern which fitted a quadratic model. DHA from Schizochytrium spp. modifies PGE2 response after the surgery in cats. The physiological roles of the DHA in the reproduction of cats were not investigated, but its gonadal deposition after supplementation was observed.
