RESUMEN

Cats are popular companion animals globally. While the general academic definition of responsible cat ownership is agreed upon, committing to responsible cat ownership is multifaceted, often reflecting regional priorities and values. Utilising a virtual private network (VPN), an English-language online search for 'responsible cat ownership' was applied from major cities in 10 different nations, accounting for five different geographic regions and nine different geographic sub-regions. Data were extracted from the first 20 webpages of each search and included author affiliation, country of webpage origin, and all recommendations towards responsible cat ownership. Searches identified 58 different webpages, 142 duplicate results, and 16 different recommendations. Both before (60.5%) and after (58.6%) duplicate exclusion, irrespective of region, most webpages originated from Australia, so recommendations may lack local nuance in other countries. Similarly, local government webpages were the most common author affiliation both before (35.5%) and after (37.9%) duplicate exclusion-moreover, most Australian webpages were authored by local government (55.9%). More than half of all webpages recommended registration and microchipping (65.5%), desexing (65.5%), and containment (60.3%), probably due to the predominance of local government and Australian webpages online-reflecting Australia's strong legislative stance. Both Australia and New Zealand showed majority recommendations for containment but not for environmental and behavioural enrichment in households. This may be partially explained by the significantly higher agreement in Australia and New Zealand that cats threaten valued wildlife in cities, towns, and rural areas. Unlike the Oceanian nations, other countries clearly recommended improved understanding and provision for cat needs, but with little evidence of support for containment. Thus, divergent welfare considerations inform major webpages associated with attitudes towards cat ownership internationally. Encouraging containment, a responsible cat ownership practice with benefits for cats and wildlife, may be more likely to succeed outside Oceania if cat welfare is emphasised instead of wildlife protection. Within Oceania, more attention could be given to enhancing the well-being of contained cats.

RESUMEN

Free-roaming dog populations ensue from irresponsible dog ownership and abandonment. The Society for the Prevention of Cruelty to Animals (SPCA) in Hong Kong SAR offers practical solutions to control dog population growth by providing a range of different birth control programs. We present the first results of a trial Trap Neuter Return (TNR) program in Hong Kong SAR; with a free-roaming dog population on Cheung Chau Island (southwest). During the 3-year study, the SPCA undertook surveys to assess population size and trapped, desexed, and, where possible, rehomed free-roaming dogs. We report that a total of 182 dogs were encountered during the period. We estimate that an average of 75% of the population was desexed, reaching the threshold for successful TNR studies. The results of our study show that TNR can assist with free-roaming dog population control and provide guidance for future programs, in Asia and Hong Kong SAR.

RESUMEN

In many Western countries, castration is the most popular surgical desexing procedure in dogs. The aim of the study was to identify the reasons for male dog castration and to determine the owners' perceptions about changes in dog behavior before and after castration. An online survey was posted on social networking sites dedicated to dogs. A total of 386 respondents participated in the survey. The main reason (39%) for castration was undesirable behavior, including hyperactivity (8%), roaming (8%), mounting (7%), aggression (5%), marking (5%) and others (5%). This surgery did not change the prevalence of aggressive behaviors towards people, but it reduced aggressive behaviors towards dogs and other animals. Castration did not reduce the presentation of anxious behavior in fearful dogs. Castration increased the number of dogs that were fearful of unfamiliar dogs/humans, as well as dogs with sound phobias, while decreased the prevalence of hiding behavior. This procedure greatly decreased incidences of roaming, mounting and urine marking as well as the dog's overall activity. Thus, it can be concluded that while castration can resolve many undesirable behaviors in male dogs, the arguments for and against neutering should always be considered on an individual basis.

RESUMEN

Cats are prolific breeders, and if most cats were desexed prior to puberty, numbers of unwanted cats and kittens, and hence numbers entering shelters, would be expected to decline. Although traditionally in Australia it has been reported that 90% of veterinary clients' cats are desexed, there are still hundreds of cats and kittens that end up unwanted and in shelter care annually. In this study, we surveyed Queensland veterinary practices to describe ages that veterinarians are recommending cats should be desexed at, ages at which desexing actually occurs, what veterinary practices are doing to promote desexing of cats, and what veterinarians see as the barriers to desexing of cats before puberty. A questionnaire was developed and sent to all veterinary practices in Queensland. The response rate was 50%. Almost 45% of respondents recommended desexing at the traditional age of 6 months, which is later than puberty in most cats; for more than 56% of practices, the actual average age at which desexing occurred was at least 6 months; and in a substantial proportion of practices, when desexed, high percentages of cats had already had litters. Most practices took steps to encourage their clients to have their cats desexed, and most thought these steps were effective. The results from this study suggest that although veterinarians generally agree that cats should be desexed prior to having their first litter, recommended and actual desexing ages are commonly too late to ensure this is achieved. Better understanding is required about both the likely impact of more veterinary practices recommending and conducting desexing before puberty on numbers of unwanted cats and numbers surrendered to shelters, and the drivers of age at which cats are desexed. This could inform strategies to reduce numbers of unwanted cats.

RESUMEN

In Australia, each state and territory authority implements and enforces regulations regarding dog management-including the breeding and sale of dogs online-which is increasingly becoming the most popular method of obtaining pets. The aims for this study included: 1. Benchmarking regulatory compliance in online dog advertisements in Australia, and, 2. Understanding factors associated with regulatory compliance in online advertisements. We collected advertisements for dogs and puppies from Gumtree-one of Australia's most popular online trading platforms - on two separate days, two weeks apart (25 March and 8 April 2019). A total of 1735 unique advertisements were included in the dataset. Chi-squared tests and multivariable logistic regression models were used to identify risk factors for microchipping, desexing and breeder identification number, and compliance levels. State laws requiring animals to be microchipped prior to sale and the inclusion of chip numbers in advertisements were found to be the biggest factor in increasing likelihood of microchipped animals in Gumtree advertisements, while desexing was more common in microchipped and older animals. The online ad was more likely to include a breeder ID if the dog was young, vaccinated, and advertised by a breeder rather than an owner. The findings from this study will assist regulators to make evidence-based decisions on managing online advertisements for companion animals. In the future, the benchmarking this study has presented will allow future analysis of the effectiveness of regulation changes.

RESUMEN

Background: Desexing dogs is promoted for population control, preventative healthcare, and behavior modification. Common methods are orchiectomy and ovariectomy/ovariohysterectomy. GnRH superagonist implants are available in some areas. Alternative methods like vasectomy and salpingectomy/hysterectomy are uncommon. The terminology used to describe desexing is inconsistent and contradictory, showing a need for the adaption of standardized terminology. Population Control: Surprisingly, empirical studies show no effects of desexing on population control in companion and shelter dogs despite desexing being consistently recommended in the literature. There is evidence for a population control effect in free-roaming dogs, where desexing also has benefits on zoonotic disease and bite risk. Population control in free-roaming dogs is mostly correlated with female, not male desexing. Health and Lifespan: Desexing affects numerous disease risks, but studies commonly neglect age at diagnosis and overall lifespan, age being by far the most important risk factor for most diseases. We argue that lifespan is a more important outcome than ultimate cause of death. A beneficial effect of desexing on lifespan is consistently demonstrated in females, while evidence for a beneficial effect in males is inconsistent. Studies are likely biased in desexing being a proxy for better care and desexed dogs having already lived to the age of desexing. Desexing reduces or eliminates common life-limiting diseases of the female reproductive system such as pyometra and mammary tumors, while no analogous effect exists in males. Disease risks increases across sexes and breeds include cruciate ligament rupture, various cancers, and obesity. Urinary incontinence risk is increased in females only. Various other disease risk changes show considerable variability between breeds and sexes. Behavioral Effects: Desexed males show reduced libido, roaming, conspecific mounting, and urinary marking frequency, as well as reduced male dog-directed aggression in a majority of males desexed for behavioral reasons. There is a detrimental effect on the risk and progression of age-related cognitive dysfunction. Desexed dogs may be less likely to cause bite injuries across sexes. The evidence for other effects such as human-directed aggression, human or object mounting, resource guarding, or shyness and anxiety is inconsistent and contradictory. There are few studies specific to females or individual breeds. Conclusions: The evidence for a beneficial effect of desexing is stronger in female than in male dogs; however, there is significant variation between breeds and sexes, and more research is needed to further elucidate these differences and to arrive at individualized evidence-based recommendations for clinical practice.

RESUMEN

Responsible cat ownership is important for keeping pet cats and wildlife safe. Much research investigating levels of compliance with and attitudes towards responsible cat ownership practices has focused on cat owners. Non-owner attitudes are relevant because their opinions may encourage cat-owning friends and family to engage (or not) in a cat management practice. The aim of this study was to determine levels of compliance with responsible cat ownership practices among cat owners, as well as attitudes towards those behaviors by owners and non-owners alike. An online survey was completed by 6808 people living in Australia who were recruited via companion animal or wildlife interest groups on social media. Frequency data were used to measure owner compliance with responsible cat ownership behaviors and t-tests were used to determine whether owners and non-owners differed in their attitudes towards these behaviors. Owner compliance with responsible practices ranged from 46.5% (complete cat containment all day and night) to 76.9% (cat is de-sexed). Owner attitudes towards these practices were generally more positive than the reported levels of management practices implemented for their own cat. For example, 47.3% of owners agreed or strongly agreed that cats should always be contained and 88.6% agreed that cats should be contained at night. Non-owners were more likely than owners to agree that cats should be contained during the day, but there was no difference for containment at night. Owners were more likely to report that cats should be de-sexed. These results can be used to inform campaigns aimed at increasing compliance with responsible cat ownership behaviors.

RESUMEN

Prepubertal desexing (neutering) has been a legal requirement for all cats and dogs in the Australian Capital Territory since 2001. All cats have to be desexed by 3 months of age, and all dogs are required to be desexed by 6 months of age. The role of veterinary attitudes and behaviors in the implementation of mandatory prepubertal desexing in the Australian Capital Territory is explored in this paper. An online survey was sent to all veterinarians registered in the Australian Capital Territory via the Veterinary Surgeons Board (VSB). The survey was designed as a cross-sectional study, hosted using the software REDcap® and analyzed using statistical program R®. A response rate of 14.9% (52/350) of registered veterinarians was achieved. Only 10% of respondents (5/52) recommended that clients have their cat desexed at 3 months of age, the legal maximum age for desexing in the jurisdiction. However, 40% of veterinarians (21/52) thought prepubertal desexing was an appropriate management strategy of cats to prevent overpopulation. Just over one-third of all veterinarians who responded (18/52; 35%) were not aware that prepubertal desexing was mandatory in the Australian Capital Territory. We conclude that prepubertal desexing might be poorly supported by veterinarians in the Australian Capital Territory, even though pets are legally required to undergo prepubertal desexing. As a result, veterinarians may unintentionally be limiting access to this procedure. This has wider policy consequences for Australian and overseas jurisdictions which are considering introducing mandatory prepubertal desexing.

RESUMEN

Aims: To describe the opinions of respondents to an online survey on desexing, microchipping and pet registration, and the management of cats, and aggressive dogs in New Zealand. Methods: A cross-sectional survey was conducted online from 18-22 June 2015 using a permission-based panel of New Zealand residents aged ≥18 years. Questions included demographics of respondents, number of dogs and cats owned, and opinions on desexing, microchipping, pet registration, management of cats and aggressive dogs. Results: Of the 1,572 survey respondents, 216 (13.7%) owned ≥1 dog and ≥1 cat, 227 (14.4%) owned ≥1 dog and no cats, 480 (30.5%) owned ≥1 cat and no dogs, and 559 (35.6%) did not own any pets. The majority of dogs (456/613; 74.8%) and cats (974/1,045; 93.2%) were desexed. The most common reasons for not desexing pets were cost, feeling that it was not needed, or keeping the dog for breeding. Of the 613 dogs, 557 (90.9%) were registered with the local council, and 434 (71.0%) were microchipped, but only 290 (47.3%) were registered in the national database. Of the 1,045 cats, 326 (31.2%) were microchipped and 279/486 (57.4%) owners felt that it was unnecessary. Of the 1,572 respondents, 947 (60.2%) were unaware of stray cats in their local community, and 479 (30.5%) stated that local councils, or animal welfare organisations (546/1,572; 34.7%) should be responsible for managing strays. Among all 1,572 respondents, 787 (50.1%) thought stray cats should be assessed and subjected to euthanasia. Compared with non-pet owners, a lower percentage of cat owners agreed that cats should be confined (p < 0.001). When asked to choose the most appropriate course of action for dogs that had bitten people or other animals, 849 (54.0%) and 820 (52.5%) respondents, respectively, agreed that the dog should be assessed by an expert who would then determine the appropriate action. Compared with non-pet owners, a lower percentage of dog owners supported registration and education of dog owners, aggressive dogs being destroyed, and giving more power to local councils (p < 0.05). Conclusions: The results highlight opportunities to improve owner compliance with desexing, microchipping and registration of dogs and cats. Opinions towards management of stray cat and aggressive dogs varied between pet owners and non-owners. Further research is needed to better understand how to engage the public in important dog and cat management policy issues.

RESUMEN

Surgical desexing of cats is typically carried out after six months of age (Mature Age Desexing, MAD); between 4⁻6 months (Traditional Age Desexing, TAD); or before four months (Early Age Desexing, EAD). We complemented existing surveys of veterinarians' acceptance of EAD with online and face-to-face surveys, to ascertain the preferred desexing ages for cats and rationale of 957 Australian veterinarians, veterinary nurses, veterinary science students, and veterinary nursing students. A complementary survey of 299 veterinary practice websites across Australia documented any information provided about desexing cats. The most common reason for preferred desexing ages was reducing stray cat populations (30%); 78% of these respondents chose ages aligning with EAD. Vet nurses and nursing students were more conservative than vets or vet students, preferring to desex cats >4 months. Perceived anaesthetic risk was a major motivation, especially for nurses ≤5 years' experience. Across 299 urban practices in Australian capital cities, 55% of surveyed websites provided no information about desexing cats or listed desexing without explaining why it was necessary, or when to perform it. Increasingly, Australian legislatures mandate desexing of cats by three months of age, so the practices of some current/future veterinary professionals do not match changing legislation.

RESUMEN

AIMS: To describe the level of experience and confidence of veterinary students in performing canine and feline desexing procedures at the end of their final clinical year. METHOD: A cross-sectional survey was conducted with veterinary students at Massey University in November 2017 after completion of their final clinical year. The questions included career plans after graduation, number of assisted and unassisted desexing procedures performed, approximate time to complete desexing surgeries, level of confidence with different aspects of desexing surgeries, what aspects of their desexing surgery training were most helpful, and what could be done to improve training in desexing surgical skills in veterinary school. RESULTS: The survey was completed by 70/95 (74%) students in their final clinical year. Among respondents, 55/70 (70%) had performed >2 unassisted feline neuters before graduation. However 38/70 (54%) students had never performed an unassisted feline spay, 31/70 (44%) had never performed an unassisted canine neuter, and 44/70 (63%) students had never performed an unassisted canine spay. The median reported times to complete a feline neuter, feline spay, canine neuter, and canine spay were 9, 40, 30 and 60 minutes, respectively. The median level of confidence for these procedures were 9, 6, 7 and 5 (on a scale from 1=least confident to 10=most confident), respectively. The reported time to complete procedures and the confidence in performing procedures did not change markedly with increasing total number of procedures performed. Students were most concerned about their ability to perform the desexing procedures in a reasonable amount of time and to prevent post-operative bleeding from occurring. Students were least concerned with their ability to manage post-operative pain in patients and to select the appropriate suture material. Free-text comments revealed that 62/70 (89%) students wanted more hands-on surgical experience prior to graduation. CONCLUSION AND CLINICAL RELEVENCE: Many students are currently completing veterinary school with limited experience and low confidence with performing routine canine and feline desexing procedures. Further research is needed to identify the most effective ways for addressing this issue within the constraints of the veterinary curriculum and teaching hospital resources.

RESUMEN

Approximately 50% of cats admitted to Australian shelters are kittens, and 26% of dogs are puppies, and, particularly for cats, euthanasia rates are often high. Cats can be pregnant by 4 months of age, yet the traditional desexing age is 5-6 months, and studies in Australasia and Nth America reveal that only a minority of veterinarians routinely perform early age desexing (EAD) of cats or dogs, suggesting they are not graduating with these skills. This study aimed to describe the attitudes of veterinary teaching staff in Australian and New Zealand universities towards EAD, and to determine if these changed from 2008 to 2015. It also aimed to identify students' practical exposure to EAD. Most (64%) of the 25 participants in 2015 did not advocate EAD in their teaching and, in their personal opinion, only 32% advocated it for cats. Concerns related to EAD cited by staff included anesthetic risk, orthopedic problems, hypoglycemia, and, in female dogs, urinary incontinence. Those who advocated EAD cited benefits of population control, ease of surgery and behavioral benefits. Only three of the eight universities provided a majority of students with an opportunity to gain exposure to EAD procedures before graduation, and in two of these, most students had an opportunity to perform EAD. In conclusion, most veterinary students in Australia and New Zealand are not graduating with the knowledge or skills to perform EAD, and have little opportunity while at university to gain practical exposure. Welfare agencies could partner with universities to enable students to experience EAD.

RESUMEN

BACKGROUND: Desexing percentages for pet cats in Australia are nearly 95%, but the high numbers of unwanted kittens surrendered to animal shelters suggest that many pet cats breed before the owners consider desexing, or that the mothers of many of these kittens are stray or feral. METHODS AND RESULTS: A convenience sample of Western Australian pet cats of known age presented for microchipping (584 in 2012 and 316 in 2013) found that younger cats were less likely to be desexed. In 2012, 93.2% of cats aged ≥2 years were desexed compared with 49.4% of cats <2 years old, with the data for 2013 being 97.4% and 28%, respectively. CONCLUSION: If these results are reflected nationally, desexing of prepubescent cats up to 4 months old could significantly reduce the numbers of unwanted kittens born to pet cats.
