Puppy Socialisation Experiences in Relation to Age and COVID-19 Lockdown Restrictions in the UK and ROI.

Limited socialisation can contribute to the development of undesirable dog behaviours. The COVID-19 lockdown potentially limited socialisation opportunities, which may negatively impact the future behaviour of puppies raised during lockdown. Data were gathered from longitudinal study participants in the United Kingdom/Republic of Ireland via multiple questionnaires between May 2016 and November 2022. The impact of age and lockdown phase (pre-, during, and post-) on the types of socialisation experiences of 8-to-19-week-old puppies and the recency of socialisation experiences of approximately 6-month-old puppies were examined. Puppies under 19-weeks had significantly more types of socialisation experiences (from a predefined list) as they aged, and pre-lockdown compared to post-lockdown, but not between other lockdown phases. Most 6-month-old puppies had met a new adult or dog outside the household, a familiar dog, and/or a child within the last 1-7 days, and this was similar between lockdown phases. During lockdown, 6-month-old puppies experienced longer periods between meeting a new adult in their home. Puppies were hypothesised to have had fewer experiences during lockdown, but this was not found. However, the quantity and quality of these experiences may have been affected. Future research within this longitudinal study will explore relationships between the timing and type of experiences had by puppies and their subsequent behaviour.

GenPup-M: A novel validated owner-reported clinical metrology instrument for detecting early mobility changes in dogs.

OBJECTIVE: To use a previously validated veterinary clinical examination sheet, Liverpool Osteoarthritis in Dogs (LOAD) questionnaire, combined with kinetic and kinematic gait analysis in dogs with/without mobility problems to demonstrate the capacity of a novel clinical metrology instrument ("GenPup-M") to detect canine mobility impairments. DESIGN: Quantitative study. ANIMALS: 62 dogs (31 with mobility impairments and 31 without mobility impairments). PROCEDURE: The dogs' clinical history was obtained from owners and all dogs underwent a validated orthopaedic clinical examination. Mobility impairments were diagnosed in the mobility impaired group based on clinical history and orthopaedic examination. Owners were asked to complete GenPup-M along with a previously validated mobility questionnaire (Liverpool Osteoarthritis in Dogs (LOAD)) to identify construct validity. As a test of criterion validity, the correlation between instrument scores and the overall clinical examination scores, along with force-platform obtained peak vertical forces (PVF) were calculated. GenPup-M underwent internal consistency and factor analysis. Spatiotemporal parameters were calculated for dogs with/without mobility impairments to define the gait differences between these two groups. RESULTS: Principal Component Analysis identified GenPup-M had two components with Eigenvalues >1 ("stiffness/ease of movement" and "willingness to be active/exercise"). Cronbach's α was used to test internal consistency of GenPup-M and was found to be "good" (0.87). There was a strong, positive correlation between GenPup-M and LOAD responses (r2 = 0.69, p<0.001) highlighting construct validity. Criterion validity was also shown when comparing GenPup-M to clinical examination scores (r2 = 0.74, p<0.001) and PVF (r2 = 0.43, p<0.001). Quantitative canine gait analysis showed that there were statistically significant differences between peak vertical forces (PVF) of mobility impaired and non-mobility impaired dogs (p<0.05). Analyses of PVF showed that non-mobility impaired dogs more evenly distributed their weight across all thoracic and pelvic limbs when compared to mobility impaired dogs. There were also consistent findings that mobility impaired dogs moved slower than non-mobility impaired dogs. CONCLUSION AND CLINICAL RELEVANCE: GenPup-M is a clinical metrology instrument (CMI) that can be completed by dog owners to detect all mobility impairments, including those that are early in onset, indicating the versatility of GenPup-M to assess dogs with and without mobility impairments. Results of the study found that GenPup-M positively correlated with all three objective measures of canine mobility and consequently showed criterion and construct validity. Owner-reported CMIs such as GenPup-M allow non-invasive scoring systems which veterinary surgeons and owners can use to allow communication and longitudinal assessment of a dog's mobility. It is anticipated that GenPup-M will be used by owners at yearly vaccinations/health checks, allowing identification of any subtle mobility changes, and enabling early intervention.

"It's Like Living with a Sassy Teenager!": A Mixed-Methods Analysis of Owners' Comments about Dogs between the Ages of 12 Weeks and 2 Years.

Owners' understanding of dog behaviour influences dog welfare. This study aimed to investigate owners' experiences of living with dogs and perceptions of dog behaviour/behaviour change. Data from an ongoing UK/ROI longitudinal study of dogs were used. Open-ended survey data (n = 3577 comments, n = 1808 dogs) when dogs were 12/16 weeks (data combined), 6, 12, 18 and 24 months were analysed to cover the dog's puppyhood/adolescence. To evaluate the usefulness of open-ended survey questions, both quantitative textual and qualitative thematic analyses were employed. Textual analysis identified an overall positive sentiment at all timepoints; the proportion of positive: negative sentiments increased with the dog's age. Words related to 'love' were the most frequent descriptors at all but the first timepoint, when 'bite' was the most frequent descriptor. Qualitative analysis helped to identify that owners attribute dog behaviour to 'Dog's biology', 'Personality/deliberate action' and 'External influences'. Analysis of open-ended survey responses helped to identify changes in perception over time. When dogs were young, owners described problematic behaviours as 'mischievous', unintentional and context-specific. Similar behaviours shown by older dogs were seen as 'deliberate'. Both positive and negative experiences of dog ownership were identified. However, as not all respondents answered open-ended questions, the generalisability of our findings is limited.

Introducing a Puppy to Existing Household Cat(s): Mixed Method Analysis.

Although cats and dogs can live amicably, inter-species conflict can result in poor welfare. Species introduction can impact the development of the cat-dog relationship. This study aimed to identify factors associated with owner reported 'only desirable' puppy behaviour (defined as the puppy being uninterested, ignored the cat and/or interacted in a calm way) following introduction to existing household cats, and to explore perceptions of the emerging cat-dog relationship. Owner-reported data collected as part of a longitudinal study of canine health and behaviour were used. Of 4678 puppies, 26.7% lived with at least one cat. Of the 1211 puppies who had been introduced to the household cat at the time of survey completion, playing (58.9%), being overexuberant or over-excited (56.6%), and chasing (48.6%) were the most common behaviours displayed towards cats. 'Only desirable' behaviours were shown by 7.3% of puppies. Multivariable logistic regression showed early (puppies aged <12 weeks), gradual introductions and living in a multi-dog household increased the odds of 'only desirable' behaviours. Qualitative analysis revealed two styles of introductions­owner-led and pet-led. Owners who led introductions anticipated amicable relationships between pets, whilst owners who let pets introduce themselves did not. Early, gradual, owner-led introductions of puppies to household cats should be encouraged.

Accessing veterinary healthcare during the COVID-19 pandemic: A mixed-methods analysis of UK and Republic of Ireland dog owners' concerns and experiences.

BACKGROUND: This study explored dog owners' concerns and experiences related to accessing veterinary healthcare during the COVID-19 pandemic. METHODS: Data were obtained through two cross-sectional owner-completed surveys conducted in May (first nationwide lockdown) and October 2020 and owner-completed diaries (April-November 2020). Diaries and relevant open-ended survey questions were analysed qualitatively to identify themes. Survey responses concerning veterinary healthcare access were summarised and compared using chi-square tests. RESULTS: During the initial months of the pandemic, veterinary healthcare availability worried 32.4% (n = 1431/4922) of respondents. However, between 23 March and 4 November 2020, 99.5% (n = 1794/1843) of those needing to contact a veterinarian managed to do so. Delays/cancellations of procedures affected 28.0% (n = 82/293) of dogs that owners planned to neuter and 34.2% (n = 460/1346) of dogs that owners intended to vaccinate. Qualitative themes included COVID-19 safety precautions, availability of veterinary healthcare and the veterinarian-client relationship. CONCLUSION: Veterinary healthcare availability concerned many owners during the COVID-19 pandemic. Access to veterinary healthcare for emergencies remained largely available, but prophylactic treatments were delayed for some dogs.

Impact of Changes in Time Left Alone on Separation-Related Behaviour in UK Pet Dogs.

Separation-related behaviours (SRBs), including but not limited to vocalisation, pacing, destruction and toileting, occur in the absence of human company. As well as being problematic for the dogs' owners, such behaviours indicate that the dogs' emotional state is compromised. As part of the COVID-19 pandemic, time spent alone decreased considerably for many pet dogs, leading to concerns about the development of SRBs when dogs are left alone more again. The main aim of this study was to test the hypothesis that dogs whose time left alone decreased most (compared to a February 2020 pre-COVID baseline) would be at greatest risk of developing new signs of SRB when time left alone increased again. To achieve this aim, we utilised survey data gathered from dog owners between 4th May and 3rd July 2020, during the first COVID-19 'lockdown' period in the United Kingdom (UK), and a follow-up survey of the same dog-owner cohort, completed when restrictions had eased between 10th October and 2nd November 2020. Individual dogs fluctuated considerably in whether they showed signs of SRB or not across the study period (n = 1807). Overall, the prevalence of SRB in the population decreased from 22.1% to 17.2%, as did the time dogs were left alone for between February and October 2020. However, 9.9% of dogs had developed new signs of SRB by the follow-up survey in October 2020, with dogs whose leaving hours decreased most during lockdown restrictions being at increased risk of developing SRBs. These findings have implications for our understanding of the etiology of SRB, by showing a link between changes in owner routine and SRB risk.

Age of sexual maturity and factors associated with neutering dogs in the UK and the Republic of Ireland.

BACKGROUND: Surgical neutering of dogs is common, however the average age that dogs reach sexual maturity, are neutered, and dog owners' attitudes to neutering in the UK and the Republic of Ireland have not been explored in a longitudinal study. METHODS: Owner-reported data on the timing of the first oestrus, timing of neutering and the reasons given for neutering dogs by 12 and 15 months of age were summarised. Factors associated with neutering at 15 months and factors associated with intention to neuter were quantified using multivariable logistic regression. RESULTS: At 15 months of age, 90.0% (n = 207/230) of unneutered females had had their first oestrus. By 7, 9, 12 and 15 months of age, 22.1% (n = 131/593), 32.2% (197/593), 45.4% (n = 269/593) and 59.9% (n = 352/593) of dogs were neutered, respectively. Breed purity, dog's source, owners' intentions to neuter and the number of dogs in the household were associated with neuter status at age 15 months. Dog's sex, Kennel Club registration, dog's source, dogs intended to be working dogs and previous dog ownership were associated with intentions to neuter. Preventing puppies was the most common reason for neutering. CONCLUSION: Understanding factors that shape owners' intentions to neuter can inform owner-vet discussions regarding whether to neuter a dog and the optimal age for doing so.

Cognitive and Composite Behavioural Welfare Assessments of Pet Cats between the Ages of 9-22 Months, Living in Single and Multi-Cat Households.

Although agonistic interactions between cats are often regarded clinically as a source of stress, there is currently limited research evidence regarding the welfare impact of keeping multiple cats as pets. The aim of this study was to compare welfare indicators between cats living in domestic single and multi-cat households, as well as between multi-cat households where agonistic behaviour was/was not reported by owners. Indicators included a spatial judgment bias task (JBT), where longer latencies to ambiguous probes are interpreted as being related to a more 'pessimistic' mood state, and the cat stress score (CSS), where high scores are indicative of high stress levels. Of 128 focal cats between the ages of 9-22 months, 94 were from multi-cat households, 126 had useable CSS data and 42 had JBT results suitable for analysis. CSSs were significantly lower for cats showing a more 'pessimistic' response in the JBT. It is possible that the cats that appeared to be the most relaxed may have been showing inactivity relating to negative affective states and/or were the least active/food motivated, and therefore slower in the JBT. CSSs were significantly higher in cats from single compared with multi-cat households, and did not vary with reports of agonistic interactions in multi-cat households. JBT results did not vary depending on the presence of, or reports of agonistic behaviours between, cohabiting cats. These data suggest that cats from single-cat households may be more likely to show signs of acute stress than those in multi-cat households. Alternative explanations are possible. For example, lower CSSs in the multi-cat group may reflect 'relief' effects resulting from separating cats for the test period, or inactivity relating to negative affective states. Due to the narrow sample population and broad scope of husbandry conditions, the potential for confounding variables limits the degree by which results can be used to inform causation of the relationships identified. Further research is warranted to replicate this work and explore potential confounders.

"More Attention than Usual": A Thematic Analysis of Dog Ownership Experiences in the UK during the First COVID-19 Lockdown.

On 23 March 2020, the UK Government imposed a nationwide lockdown as part of efforts to mitigate the impact of COVID-19. This study aimed to explore how the experience of dog ownership in the UK was impacted during this lockdown. Data for this research came from open-ended survey questions and an electronic diary completed by members of the general public and participants involved in "Generation Pup", an ongoing longitudinal cohort study of dogs. A total of 10,510 free-text entries were analysed. Three major themes emerged: spending time at home with dog(s), walking practices, and behaviour and training. Owners valued having more time than usual with their dog(s) but also recognised that spending extra time with their dog(s) may negatively impact on the dog's future ability to cope when left alone. However, very few owners provided alone time for their dog(s) during the lockdown. The opportunity to walk their dog(s) as part of their permitted daily exercise was regarded positively, but walks under the lockdown guidelines were not always felt to be adequate with respect to providing sufficient exercise and opportunities for interaction with other dogs. Owners reported observing new undesirable behaviours in their dog(s) during the lockdown, including barking and dogs being "clingy" or vocalising when briefly left alone. Based on these findings, we suggest intervention strategies to best support dog welfare that include helping dog owners to teach dogs to cope with being alone, even if owners do not need to leave their dogs alone.

Impact of the First COVID-19 Lockdown on Management of Pet Dogs in the UK.

Initial COVID-19 lockdown restrictions in the United Kingdom (23rd March-12th May 2020) prompted lifestyle changes for many people. We explored the impact of this lockdown phase on pet dogs using an online survey completed by 6004 dog owners, who provided information including dog management data for the 7 days prior to survey completion (4th-12th May 2020), and for February 2020 (pre-lockdown). We explored associations between potential predictors and four outcomes relating to changes pre-/during lockdown (reduction in number and duration of walks; increased frequency of play/training, and provision of toys). Most owners (79.5%) reported their dog's routine had changed compared to pre-lockdown. There was a four-fold increase in the proportion not left alone for >5 min on any day during a weekly period (14.6% pre-lockdown, 58.0% during lockdown), with the proportion being left for ≥3 h at a time decreasing from 48.5% to 5.4%. Dogs were walked less often and for less time daily during lockdown, with factors related to the dog, owner, household, and home location associated with changes to walking practices. Many dogs had more play/training sessions and were given toys more frequently during lockdown. Decreased walk duration was associated with increased odds of play/training opportunities and toy provision. These changes to dog management have the potential for immediate and longer-term welfare problems.

Puppy acquisition: factors associated with acquiring a puppy under eight weeks of age and without viewing the mother.

BACKGROUND: Puppy acquisition decisions may impact upon the health and behaviour of these dogs in later life. It is widely recommended by welfare organisations and veterinary bodies that puppies should not leave maternal care until at least eight weeks (56 days) of age, and that when acquiring a puppy it should be viewed with its mother. METHODS: Owner-reported prospective data were used to explore risk factors for puppy acquisition age, and whether the mother was viewed during acquisition, within a cohort of dog owners participating in an ongoing longitudinal project. RESULTS: A quarter (461/1844) of puppies were acquired under eight weeks of age and 8.1 per cent were obtained without viewing the mother (n=149). Only 1.6 per cent of puppies were obtained under eight weeks of age and without the mother being seen (n=30). Multivariable logistic regression analysis revealed that owners who intended their puppy to be a working dog, visited their puppy prior to acquisition, and/or obtained a puppy of unknown breed composition had increased odds of acquiring a puppy under eight weeks of age. The odds also increased as the number of dogs in the household increased but decreased as annual income rose. Owners who visited their puppy prior to acquisition, obtained a Kennel Club registered puppy, viewed the puppy's father, and/or collected their puppy from the breeder's home had decreased odds of acquiring a puppy without viewing the mother. CONCLUSION: Targeting interventions towards identified owners who are more likely to acquire a puppy against current recommendations could help reduce these types of acquisitions.

Influence of living in a multicat household on health and behaviour in a cohort of cats from the United Kingdom.

BACKGROUND: Living in a multicat household has been implicated as a risk factor for various feline issues, but evidence is often anecdotal or based on retrospective studies. METHODS: Data from the Bristol Cats Study, a UK longitudinal study of pet cats, were used. Cats were included if they had remained in either a single cat or multicat household between questionnaires 1 (two months old to four months old) and 5 (two-and-a-half years old). Univariable and multivariable logistic regression models were used to analyse associations between single cat/multicat households and measures of health and behaviour (overweight/obesity, abscesses/cat bites, negative interactions with owner and periuria). Multicat households were also subcategorised according to whether owners had reported agonistic behaviour between household cats. RESULTS: There was no evidence of association between household type and the likelihood of obesity, abscesses or periuria. The likelihood of negative interactions with the owner (eg, growling or hissing) was influenced by the cats' relationships; cats in non-agonistic multicat households had decreased odds of negative interactions with the owner, compared with single and agonistic multicat households (P<0.001). CONCLUSION: Living in a multicat households per se was not a risk factor for the health and behaviour issues investigated, but the intercat relationship is important.

Exploring early life events including diet in cats presenting for gastrointestinal signs in later life.

Our study aimed to determine if certain early life events were more prevalent in cats presenting to veterinary practices specifically for gastrointestinal signs on at least two occasions between six months and 30 months of age. Data from an owner-completed questionnaire for 1212 cats before 16 weeks of age and subsequent questionnaires for the same cats between six months and 30 months of age were reviewed. Of the 1212 cats included, 30 visited a veterinary practice for gastrointestinal signs on two or more occasions. Of the early life events recorded, cats reported with vomiting, diarrhoea or both, and/or those not exclusively fed commercial diet(s) that meets the World Small Animal Veterinary Association (WSAVA) Global Nutrition Committee (GNC) guidelines before 16 weeks of age were more likely to visit veterinary practices specifically for gastrointestinal signs on at least two occasions between six months and 30 months of age (P<0.001, odds ratio (OR)=2.64, 95 per cent confidence interval (CI)=1.66-4.22 and P=0.030, OR=1.51, 95 per cent CI=1.04-2.22, respectively). Ensuring cats exclusively consume commercial diet(s) that meets the WSAVA GNC guidelines and further studies identifying specific aetiologies for vomiting and diarrhoea before 16 weeks of age to enable prevention may reduce the number of cats subsequently presenting to primary care veterinary practices for repeated gastrointestinal signs.

Owner-reported flea treatment measures and skin disease in cats.

OBJECTIVES: The aim of this study was to obtain information regarding the use of flea treatments and owner-reported flea infestation and skin disease. METHODS: Owners of 1150 cats were recruited into a long-term longitudinal study ('Bristol Cats' study) and asked to complete questionnaires at set time points. Questionnaires 1 and 5 were used and included data collection for kittens aged 2-4 months (T1) and at 2.5 years of age (T2). Owners were asked which brand of flea treatment, if any, was used at each time point. At T2 owners were asked if they had noted signs of skin disease or fleas on their cat within the previous 12 months and if they had sought veterinary attention for the skin disease or fleas. IBM SPSS version 23 was used for statistical analyses. RESULTS: Skin disease at T2 was reported by owners of 55/1150 (4.8%; 95% confidence interval [CI] 3.7-6.2) cats. Many owners who reported skin disease (25/55 [45.5%]; 95% CI 32.3-58.7) had not sought veterinary attention. There were 81/1150 (7.0%; 95% CI 5.6-8.5) cats with reported head shaking and/or ear scratching within the past 12 months at T2. The majority of cats (204/286; 71.3%) received prescription flea treatments at both points. Use of non-prescription flea treatment at T2 was more likely to be associated with owner-reported skin disease/flea infestation than those who used prescription flea treatment ( P <0.001). There was a significant association between the reported presence of fleas and reported presence of skin disease at T2 ( P = 0.03). CONCLUSIONS AND RELEVANCE: Despite the potential for reverse causality, the association between owner-reported skin disease and/or flea infestation in their cats and the use of non-prescription flea treatment was as expected. Use of flea treatments and, in particular, the type of ectoparasite control used (prescription or non-prescription) should be carefully assessed when managing cats with skin disease.

Field study assessing the performance of a patient-side blood test to determine neuter status in female cats based on detection of luteinising hormone.

OBJECTIVES: The aim of this study was to assess the performance of a patient-side blood test in determining neuter status in female cats. METHODS: Residual blood samples from female cats of unknown neuter status that were admitted to four cat adoption centres in the UK were tested for luteinising hormone (LH) using the Witness LH test (Zoetis). A positive LH test result indicated that the cat was neutered. Cats were assessed for evidence of a surgical scar suggestive of prior neutering; if none was found, an exploratory laparotomy was performed to confirm neuter status. The LH test performance was assessed (sensitivity, specificity, negative and positive predictive value). RESULTS: Two hundred and thirty-six cats had both LH test and exploratory laparotomy data. The specificity of the test in detecting neutered cats was 100% (95% confidence interval 96.2-99.9) and the sensitivity was 69% (95% confidence interval 59.3-76.8). The prevalence of neutered cats in this sample was 49%. The positive and negative predictive values were 1 and 0.77, respectively. CONCLUSIONS AND RELEVANCE: The Witness LH test correctly detected all unneutered cats and thus there were no false-positive results that incorrectly indicated a cat was neutered. This study therefore suggests that positive LH test results avoid the need to perform surgery to confirm neuter status. This has significant welfare benefits for cats as it provides a lower risk, faster and less traumatic alternative to surgery and, in the shelter setting, it will have a positive impact on the cost, speed of assessment and time to rehoming of cats.

Assessing the impact of a regional UK feline neutering campaign.

Neutering is key to feline population control. Neutering campaigns provide education and/or financial assistance to encourage neutering. This study assessed the impact of the Cats Protection East Midlands Neutering Campaign (CPEMNC) on the proportion and ages of cats neutered. The CPEMNC, comprising of an outreach programme and voucher-based subsidised neutering scheme, began in June 2014. A convenience sample of owners who had attended 12 regional veterinary practices to complete a cat vaccination course in June/July 2014, or to have their cat neutered in October 2014 (CAMPAIGN) were compared with an equivalent control period in 2013 (CONTROL). Data collected by postal questionnaire revealed that the proportion of cats neutered by six months of age was significantly higher and the age at neutering significantly lower in the CAMPAIGN (n=134) versus the CONTROL groups (n=100). Results of multivariable logistic regression indicated cats were significantly more likely to be neutered by six months of age if they were in the CAMPAIGN group (OR 2.44) and male (OR 2.17), compared with in the CONTROL group and female. Further work is needed to evaluate factors important for campaign success and to explore the effectiveness of campaigns within the wider community and across the UK.

Clinicopathological features and comorbidities of cats with mild, moderate or severe hyperthyroidism: a radioiodine referral population.

OBJECTIVES: This study sought to explore the clinicopathological features and comorbidities of cats with mild, moderate and severe hyperthyroidism in a radioiodine referral population. METHODS: Medical records were reviewed, along with results of serum biochemistry, urinalysis, systolic blood pressure and diagnostic imaging performed at the time of radioiodine referral. Cats were grouped by total thyroxine (TT4) levels as mildly (TT4 60.1-124.9 nmol/l), moderately (TT4 125-250 nmol/l) or severely (TT4 >250 nmol/l) hyperthyroid at the time of diagnosis and referral. RESULTS: Thirty percent (42/140) of the cats were <10 years old at diagnosis. In 24.3% (34/140), hyperthyroidism was diagnosed incidentally. The time between diagnosis and referral for radioiodine was significantly longer in cats with severe hyperthyroidism at the time of referral ( P = 0.004). An increase in severity group between the time of diagnosis and referral occurred in 38.6% (54/140) of cats. At referral, 54.3% (25/46) of cats with mild, 66.7% (42/63) with moderate and 80.6% (25/31) with severe hyperthyroidism were unstable despite ongoing medical or dietary management. The prevalence of cardiac abnormalities was significantly increased in cats with severe hyperthyroidism ( P = 0.014) compared with those with mild or moderate hyperthyroidism. There was no significant difference in the likelihood of renal disease ( P = 0.708) or hypertension ( P = 0.328) between the groups. CONCLUSIONS AND RELEVANCE: Incidental diagnosis of hyperthyroidism occurs commonly, potentially owing to increased disease screening. Cats with severe hyperthyroidism at referral were more likely to be chronically hyperthyroid with a history of poor stabilisation. This subset of patients was significantly more likely to have cardiac abnormalities. Thyrotoxic cardiomyopathy may ultimately affect patient suitability for curative treatments (radioiodine or thyroidectomy) owing to higher anaesthetic risks and potential for decompensation into congestive heart failure with the stress of travel and hospitalisation. Curative therapy should be considered before the development of severe hyperthyroidism.

Risk factors for redemption of feline neutering vouchers issued by welfare organisations.

Animal welfare organisations in the UK invest substantial resources to fund subsidised neutering vouchers to increase feline neutering rates. Little evidence exists to quantify factors influencing voucher redemption. This cross-sectional study assessed risk factors (including voucher value and expiry period) for redemption of neutering vouchers issued by staff of the feline welfare charity Cats Protection. Data were collected using telephone interview-administered questionnaires of cat owners who were issued a neutering voucher(s) and from Cats Protection voucher payment records. During the four-month study 2655 owners were issued 3935 vouchers. Multivariable logistic regression analysis revealed that owners of cats that had produced ≥1 litter before voucher request, owners eligible for a voucher due to receiving benefits and owners who rented their homes or lived with family were less likely to redeem vouchers than owners whose cats had not had a litter, were eligible for a voucher for other reasons and/or owners who owned their home, respectively.

Owner-reported lower urinary tract signs in a cohort of young cats.

Objectives The most common cause of lower urinary tract signs (LUTS) in cats under the age of 10 years is feline idiopathic cystitis (FIC). The prevalence of LUTS in the UK pet cat population is difficult to assess. This study used data collected prospectively to investigate the prevalence of, and risk factors for, owner-reported LUTS in a cohort of young pet cats. Methods Cat owners were recruited into a long-term longitudinal study and asked to complete questionnaires at specified age points for their cats. All cats were at least 18 months of age at the time of analysis. The prevalence of owner-reported LUTS at 18, 30 and 48 months of age was calculated, based on whether the owner had seen the cat urinating, and whether the cat had displayed one or more of the following clinical signs: dysuria, haematuria or vocalising during urination. A case-control study to investigate the risk factors for owner-reported LUTS in study cats at age 18 months was also conducted, using a multivariable logistic regression model. Results The prevalence of owner-reported LUTS in cats seen urinating by the owner was 4.3%, 3.8% and 6.0%, with 95% confidence intervals of 3.2-5.7%, 2.5-5.7% and 3.4-10.5% at ages 18, 30 and 48 months, respectively. An indoor-only lifestyle at the age of 18 months and a change in diet between the ages of 12 and 18 months were identified as risk factors for owner-reported LUTS at the age of 18 months from the multivariable model. No clear type of change in diet was identified in our sample of cats with LUTS. Conclusions and relevance The prevalence of owner-reported LUTS in a cohort of young pet cats was higher than the previously reported prevalence of LUTS in cats presenting to veterinary hospitals for LUTS or other reasons. A novel risk factor of change in diet between 12 and 18 months of age warrants further investigation.
