Efficacy of the Feliway® Classic Diffuser in reducing undesirable scratching in cats: A randomised, triple-blind, placebo-controlled study.

Scratching the environment is a natural behaviour that cats use for communication and physical maintenance purposes, however when it is carried out on household furniture it is considered unacceptable for some owners and even grounds for relinquishment of cats. The objective of this study was to investigate the efficacy of FELIWAY® Classic Diffuser in reducing undesirable scratching (scratching vertical surfaces indoors other than the scratching post) in cats. A 28 day, randomised, triple-blind, placebo-controlled study with a total of 1060 caregiver-cat dyads was conducted. The study contained two groups: the Pheromone Group consisted of caregivers who were given a pheromone diffuser (n = 546) and the Placebo Group consisted of caregivers who were given a placebo diffuser (n = 514). A questionnaire with three subsections was distributed online. The first section, completed by the respondents at day 0, inquired about the cats' daily routines, social and physical environments, behaviour, temperament, and emotional states. The second section filled on day 0, 7, 14, and 28, assessed the Frequency and the Intensity of the undesirable scratching problem and the effectiveness of the product. The last section, filled on the 28th day of the product application, related to the caregivers' opinions about the product and overall outcome. After 28 days the scratching Frequency reduced for 83.5% of the cats in the Pheromone Group and 68.5% for the Placebo Group (p<0.0001). The Intensity was significantly different between treatment groups at D7 (p = 0.0170), at D14 (p = 0.0189) and at D28 (p<0.001). The reduction of the Global Index Score, which was calculated by multiplying the Intensity with the Frequency, was significantly higher for the Pheromone Group (p<0.001). This study provides direct evidence that the use of FELIWAY® Classic diffuser significantly reduces the Frequency, Intensity and the Global Index Score of undesirable scratching.

Behavioural responses to separation from human companion in the domestic cat: A survey-based study.

The domestic cat is known to react to social separation, though the conceptual relationship between separation-related behaviours outside of a clinical context has not been described in detail. We did an online survey on participants who had cats in their households (Nparticipants=114; Ncats=133) and asked them to evaluate the frequency of 12 behavioural elements associated with social separation from human companions on a 5- point Likert Scale. We performed two dimensionality reduction techniques (component and factor analyses) to assess whether the specified behaviours related to social separation belonged to the same axis. We found four distinct dimensions instead of one: (a) reactivity towards companion departure cues, (b) protest behaviour towards inaccessibility, (c) unusual elimination behaviour, and (d) negative responses following social separation. Our findings suggest a manifestation of different motivational states rather than a single, separation-related construct. Future studies would benefit from a careful evaluation of the separation-related behaviours in a multi-measure context to improve the accuracy of ethological classifications.

Factors behind the Relinquishment of Dogs and Cats by their Guardians in Portugal.

In Portugal, the relinquishment of dogs and cats is a major problem. Thus, the authors developed a questionnaire to understand the factors influencing the relinquishment of companion animals in Portugal. With a view to analyze the factors behind relinquishment by companion animal guardians, the authors analyzed surveys completed by 72 participants, divided into two groups: REL (relinquisher, n = 36), i.e., guardians who had relinquished a companion animal and NREL (non-relinquisher, n = 36) i.e., guardians who had never relinquished a companion animal. The only significant factors for the REL group were the presence of children and the type of dwelling (apartment). Additionally, the duration of guardianship of the companion animal before relinquishment (REL group) was significantly shorter if there were children in the household than if there were no children.

Domestic dogs (Canis familiaris) grieve over the loss of a conspecific.

Behavioural reactions towards a dead conspecific have been observed rarely in wild canids and there is no documented scientific evidence of grief in pet dogs. A quantitative analysis of grief-related responses in both dogs and owners was conducted, using the validated online Mourning Dog Questionnaire. The survey was completed by 426 Italian adults who had owned at least two dogs, one of whom died while the other was still alive. This research aims to explore whether, how and what a dog may experience over the loss of a companion dog. Multiple logistic regression indicates that both a friendly or parental relationship between two dogs but also the fact that dogs used to share food and the owner's grief and anger are principal predictors of negative behavioural changes. According to dog owners' answers, the surviving dog after the death of the companion dog changed both in terms of activities ("playing", "sleeping", and "eating") and emotions (fearfulness), which occurred as a function of the quality of the relationship between the two animals. By contrast, the time the two dogs had spent together had no effect on the behaviours of surviving dog. Owner perceptions about their dog's reactions and emotions were not related to the memory or suffering of the event that tended to diminish over time. These findings indicate that a dog may show grief-related behavioural and emotional patterns when a close conspecific dies, with aspects of the latter possibly related to the owner's emotional status.

An Evaluation of Portuguese Societal Opinion towards the Practice of Bullfighting.

Bullfighting is a controversial sport that continues to be legally permitted in a number of countries around the world, including Portugal. The spectacle has attracted significant attention from animal protectionist groups for many years because of concerns for animal distress, pain, and suffering during the fights. While there has been strong support for the sport in Portugal in the past, there is a need to study social profiles regarding the acceptability of this sport before a case can be made for changes in regional and national legislation. In this study, Portuguese attendance patterns at bullfights were assessed in addition to public opinions on welfare and ethical aspects of bullfighting, based on demographic variables. Study participants (n = 8248) were largely recruited through Portuguese social media channels (respondents may not be representative of the Portuguese population). Questionnaire data were evaluated by means of frequency tables, multiple correspondence analyses, and a two-step cluster analysis. Most respondents had a negative opinion about bullfighting and perceived that bullfighting had no positive impact on the country. However, while most respondents thought that the bull suffered during bullfighting, the opinion regarding banning bullfighting was far from unanimous. Based on the demographic analysis, the profile of individuals with more favorable responses towards bullfighting were men > 65 years old, of Roman Catholic faith, of low- or high-income levels, from more rural areas of Portugal. Somewhat surprisingly, there was a tendency to favor bullfighting amongst veterinary professionals. We conclude that there were still large pockets of individuals who desire to maintain the practice of traditional bullfighting within Portuguese society, despite recognition of animal suffering during the event.

The relationship between problem-solving ability and laterality in cats.

The association between hemispheric asymmetries and cognitive ability is one of the key areas of comparative laterality research. In several animal species, individual limb preferences correlate with perceptual, cognitive, or motor abilities, possibly by increasing dexterity of one limb and minimizing response conflicts between hemispheres. Despite this wealth of research, the association between laterality and cognitive abilities in the cat (Felis catus) is not well understood. Therefore, it was the aim of the present study to investigate the relationship between laterality and problem-solving ability in cats. To this end, strength and direction of paw preferences in 41 cats were measured using two novel food reaching tasks in which the animals needed to open a lid in order to reach the food reward. We found that cats that showed a clear preference for one paw were able to open more lids succesfully than ambilateral animals. Moreover, cats that preferred to interact with the test apparatus with their paw from the beginning, opened more lids than cats the first tried to interact with the test apparatus using their heads. Results also suggested a predictive validity of the first paw usage for general paw usage. It was also shown that the cats' individual paw preferences were stable and task-independent. These results yield further support to the idea that lateralization may enhance cognitive abilities.

Pet Humanisation and Related Grief: Development and Validation of a Structured Questionnaire Instrument to Evaluate Grief in People Who Have Lost a Companion Dog.

People often develop strong emotional connections with their dogs and consider them to be members of the family. The purpose of this study was to develop a novel validated tool, the Mourning Dog Questionnaire, to recognise and evaluate the mourning process in people who have lost a dog. The research model was based on a grid of five different questionnaires: the Pet Bereavement Questionnaire, the Lexington Attachment to Pets Scale, the Animal-Human Continuity Scale, the Positivity Scale, and the Testoni Death Representation Scale. The Italian version of the survey was posted on social networks. A sample of 369 Italian dog owners filled in the questionnaire (mean age ± SD 42.00 ± 10.70 years). Reliability indices were good for all instruments. The total scores of the five questionnaires correlated with each other. The results from the Mourning Dog Questionnaire support the negative view of life after the death of a pet and people's tendency to humanise their pet, since dog owners perceived animals no differently from humans in terms of emotions, needs and legal rights. Findings arising from the use of the Mourning Dog Questionnaire will help the implementation of rationality-based strategies to improve the wellbeing, resilience and quality of life of people in the world experiencing the loss of a pet.

Functional cerebral asymmetry in dogs living under different environmental conditions.

Investigating the link between stress and functional cerebral asymmetry (FCA) has been a subject of interest in recent years. The demonstration of this link in the field of veterinary medicine is particularly important as measuring FCA has the potential to be an alternative and non-invasive behavioral method to assess stress in dogs. The present study aimed to investigate whether FCA is affected by different environmental conditions in dogs. The main aim of this study was to investigate the changes in FCA in dogs living under different conditions. To this aim, strength and direction of FCA in 40 urban free-ranging dogs were measured by a Kong test. Dogs were divided into four groups considering their environmental conditions: The dogs in Group 1 (n = 8) were rehabilitated urban free ranging dogs, which were kept in enriched shelter conditions. The dogs in Group 2 (n = 9) were adopted free ranging dogs, which lived in home environment for more than 1 year. The dogs in Group 3 (n = 11) were urban free ranging dogs, which stayed in individual cages in a dog shelter for more than 6 months. The dogs in Group 4 (n = 12) were adopted urban free ranging dogs, which stayed in a dog pension for more than 30 days. Considering the length of their stay in a kennel environment, quality of living condition and emotional states, the dogs in Group 3 and 4 were classified as chronically stressed dogs. Statistically significant differences existed between groups considering strength and direction of lateralization. Most of the dogs in Group 1 (87.5 %) and Group 2 (77.8 %) showed significant paw preferences, whereas most of the dogs in the Group 3 (72.7 %) and Group 4 (75 %) were categorized as ambilateral. Considering the individual level asymmetry in dogs and environmental conditions of dogs in Group 3 and 4, one may suggest that high ambilaterality levels is related with chronic stress. Thus, reduced FCA may not be the reason for stress sensibility, rather it can be an outcome of stressful situations. These results are the first to demonstrate the possible link between chronic stress and ambilaterality in dogs.

Improving the feline veterinary consultation: the usefulness of Feliway spray in reducing cats' stress.

OBJECTIVES: Going to the veterinary clinic is a stressful experience for most cats as they feel threatened when entering a new and confined environment. The aim of this research was to investigate if Feliway spray, when used on the table in the consultation room, can decrease cats' stress and ease their handling. METHODS: A randomised, double-blind, placebo-controlled clinical trial was developed, using a total sample of 87 cats of both sexes, castrated or intact, of any breed, aged >26 weeks. A Feliway spray and a placebo solution spray were tested in two different consultation rooms. During the first phase, Feliway spray was applied to the examination table of one room and the placebo spray in the other. After a washout period of 15 days the spray allocation was switched. After the first 15 mins of general questioning and physical examination carried out by the veterinarian, the observer assessed the stress levels of the cats based on a seven-level 'cat stress score', and the ease of handling based on a five-point 'scale of handling' developed by the authors. RESULTS: The study demonstrated that the use of Feliway spray leads to significant (P = 0.01) differences in cats' usual behaviour, according to their owners. With regard to stress, animals exposed to Feliway spray showed significantly lower stress levels than those treated with placebo (P = 0.02). Regarding the scale of handling, the scoring did not differ significantly between cats under the effect of Feliway spray and cats receiving placebo (P = 0.01). CONCLUSIONS AND RELEVANCE: This research shows that the use of Feliway spray on the examination table improves the welfare of cats by reducing their stress during veterinary consultations. Feliway spray significantly changed the behaviour of the cats in this study, and offers a simple and effective way to help decrease stress in cats during the consultation.
