Play and welfare have long been linked within animal research literature, with play considered as both a potential indicator and promoter of welfare. An indicator due to observations that play is exhibited most frequently in times when an animal's fitness is not under threat and when immediate needs such as food, water and adequate space are met. And a promoter, because of observations that animals who play more also have better welfare outcomes. However, limited research has been undertaken to investigate this link, especially in companion animals. The domestic cat (Felis catus) is one of the most popular companion animals in the world, yet little is known about the impact of play behaviour on cat welfare. We review the current literature on play and welfare in cats. This includes examining the role of cat play in mitigating negative welfare outcomes, such as reducing problem behaviours, one of the leading reasons for guardian dissatisfaction and cat relinquishment to shelters. Play is also discussed as a potential tool to provide environmental enrichment and to improve cat-human relationships. Future areas for research are suggested. We find that further research is needed that uses a multi-faceted approach to assess how quantity, type and quality of play impact subsequent cat behaviour and welfare. Future research could also assess cat play needs and preferences as well as investigate the role of play in mitigating threats to cat welfare such as reducing problem behaviour and improving human-cat relationships. If play is an indicator and promoter of welfare, studies into the impact of play may offer an accessible approach for monitoring and improving domestic cat welfare.

Animal shelters rescue and care for society's unwanted companion animals. Nonetheless, several studies have shown that ending up in a shelter can be stressful, and that shelter husbandry can amplify and spread certain diseases. The aim of the present study was to investigate and describe husbandry policy, practices and routines as well as occurrence and prevention of diseases in Swedish cat shelters. A survey was sent to 64 potential shelters of which 39 (61%) responded. Thirty-two shelters (82%) housed cats (Felis silvestris catus) in groups; one shelter provided only solitary housing. Thirty-one shelters provided single, pair and group housing. The most common group size was 3-5 cats (59%). Ninety-two percent of responding shelters had routines and/or protocol(s) for the management of the cats, 35 had healthcare routines and 30 shelters had routines for the admission of cats. All shelters with the exception of one had quarantine, and 22 shelters (58%) vaccinated cats prior to admittance. There was a significant positive correlation between shelter size and number of reported diseases. The most common reported disease was cat ‘flu/cold, although altogether, shelters reported a low occurrence of disease. Practices differ between shelters relating to management, eg use of quarantine and vaccination routines. In Sweden, group housing is common and shelters provide cats with plenty of resources, eg hides and climbing structures, often providing outdoor access and a more ‘home-like’ environment. The possibility that providing a more ‘enriched home-like’ environment can help cats cope with the shelter environment is discussed, thereby decreasing the occurrence and transmission of infectious diseases.

Typically, animal shelters and rescues are judged on their live release rates. This research explores the relative impact that shelter traits and programmes have on positive outcomes for dogs. Using a survey of 370 animal shelters and rescues across the US, it concludes that eschewing the use of breed labels for all dogs that do not appear to be pure-bred, having a robust foster programme, and using a matching programme are correlated with higher live release and lower return rates. Resources are not wholly determinative of success — it is the programmes shelters and rescues implement, not simply their human and financial resources — that are associated with positive outcomes.

This study assessed how sound affected fear- and maintenance-related behaviour in singly housed cats (Felis silvestris catus) in an animal shelter. Two daily 30-min observation sessions (morning and evening) were made for 98 cats from admittance for ten days or until the cat was removed. Cat behaviour and presence of sound (classified by the source) were recorded by instantaneous and one-zero sampling with 15-s intervals. Each 30-min observation session was classified as ‘quiet’ or ‘noisy’ if the one-zero score for presence of sound was above or below the median of sessions at that time of day. To ensure that cats had at least two complete days of comparable observations, statistical analysis was restricted to the 70 cats (30 females, 40 males) present for two or more weekdays. Cats varied widely in the amount of fear and maintenance behaviour they performed. Males showed less fear and maintenance behaviour than females. Morning sessions consistently had much more sound than evenings, and cats showed more fear behaviour and less maintenance behaviour in the mornings. Cats showed more fear behaviour in noisy morning sessions than quiet ones, with no comparable difference in maintenance behaviour. Where sessions included a pronounced transition in sound, fear-related behaviour was more common after a transition from quiet to noisy and less common after a transition from noisy to quiet The results show that shelter cats vary greatly in their responses and suggest that sound in shelter environments can substantially affect their behaviour. Lowering sound levels in shelters may help improve cat welfare.

Childhood experiences of animals and current attitudes towards animals were assessed using a questionnaire, which was completed by 227 Japanese students and 174 British students. Pet ownership in childhood, as well as contact with other animals and negative experiences of pets, were used as the independent variables; current attitudes towards pets and other animals were the dependent variables. There were some differences between Japan and the UK: in childhood, the British students had had significantly more pets and more animal-related experiences, such as visiting animal shelters and livestock farms, than had the Japanese students. Their current attitudes were also more positive, and they showed a greater interest in animal welfare issues than did the Japanese students. In both countries there was a positive association between childhood pet-keeping and current favourable attitudes to pets, as measured by the Pet Attitude Scale. Open-ended responses also suggested that the roles of pets for children are perceived in similar ways in Japan and the UK. Adult attitudes to pets and interest in animal welfare seem to be greatly influenced in both countries by childhood experiences of animals, including pets, and may therefore be a general phenomenon.

Cat (Felis silvestris catus) shelter practices may have important implications for cats’ health and well-being. This study explored the relationship between husbandry practices and cat health in Hong Kong's shelters which are unregulated. Cat health was measured via body condition score (BCS), coat condition and signs of oculo-nasal discharge. A total of 314 cats in 24 cat shelters were assessed. A satisfactory BCS was associated with regular veterinary input, more than once per day disinfection and more than once per day change of water. The presence of oculo-nasal discharge — as a marker for upper respiratory tract infection — was associated with a lack of regular veterinary input and less frequent change of water within the shelter. A lack of regular feeding was the only factor associated with a dull coat. In summary, this study showed that certain husbandry practices had important associations with different aspects of cats’ health for cats housed in an unregulated shelter environment in Hong Kong. These findings provide evidence-based support for husbandry guidelines or regulations for cat shelters which could have a positive impact on shelter cats’ health and welfare.

The popular press frequently reports that coat colour bias negatively impacts shelter adoption rates for black domestic dogs. This phenomenon, commonly called ‘black dog syndrome’ (BDS), reportedly increases the likelihood of euthanasia for black dogs and negatively affects the length of black dogs’ time to adoption. While organisations may focus on BDS and ways to promote black dogs, it is possible that the influences of other important factors, such as sex, age and breed, may be overlooked. To evaluate the veracity of BDS and examine the impact of various phenotypic traits on shelter outcomes, we analysed four years of intake and outcome data from two animal shelters in the Pacific Northwestern United States. Results indicated that the average length of availability for adoption (LOA) for black dogs was not significantly longer than that for other coloured dogs, nor was the rate of euthanasia of black dogs significantly higher than average. On the other hand, age and breed group were consistent predictors of shelter outcomes across the two shelters. Older dogs tended to have longer LOA and to be euthanised at rates higher than expected. Bully breeds had significantly longer LOA in both shelters and, compared to other breeds, were euthanised at higher than expected rates. The methods implemented in this study could be utilised by other shelters to inform intake and marketing strategies.

The preference of Syrian hamsters (Mesocricetus auratus) for different in-cage shelters was tested. First, 15 males and 15 females were made to choose between a cage with a shelter and one without. Different shelters were tested consecutively: short (10-cm) or medium (15-cm) pipes made of black acrylonitrile butadiene styrene (ABS), 7.6 cm in diameter and open at both ends; and short or medium boxes made of black acrylic panels and open at only one end. The strongest use of the shelter cage for nesting (about 75% of days) was in the case of the medium, open pipe, for both males and females. The strongest use of the shelter itself for nesting was also in the case of the medium open pipe (52% of days). A second experiment gave a choice between pairs of shelters (of seven different types) to 10 males and 10 females. Both sexes nested significantly more in a medium pipe closed at one end than under a wheel, and tended to nest more in that medium, semi-closed pipe than in a medium, open pipe. Also, females tended to nest more in the medium, semi-closed pipe than under an aluminium cover. Other pairings did not yield significant differences. Direct use of the shelters for nesting was rather low, except for the medium, semi-closed pipe (about 50% of days). Semi-closed ABS pipes are inexpensive, easy to clean, and do not interfere with running wheels, and they could be recommended as environmental enrichment for hamsters.
