Item Surveying pet owners’ attitudes towards roaming cats in Aotearoa New Zealand(Taylor and Francis Group on behalf of the New Zealand Veterinary Association, 2025-08-24) Awawdeh L; Waran N; Pearson M; Forrest RHAim: To examine the attitudes of pet owners towards roaming cats in New Zealand. Materials and methods: Data was used from a survey of New Zealand residents aged over 18 conducted online between January and March 2019. Along with demographic questions, the respondents were asked, “Do you think that roaming pet dogs and cats are a problem?” (yes, no, never thought about it) and if they answered “yes”, were invited to explain their answers. Thematic analysis was applied to open-text responses focused on cats, while quantitative data were analysed using descriptive statistics. Results: Of a total of 2,744 participants, 2,292 answered the question regarding roaming pets, with 72% (n = 1,654) viewing roaming pets as problematic. While gender, ethnicity, and rural upbringing showed no significant association with this view, age, education level, place of residence, and pet ownership did. Explanations for their choice of answer were given by 1,479 respondents and highlighted key concerns about free-roaming pets including cats: compromised animal welfare due to risks and neglect; the need for more responsible pet ownership and owner education; calls for stricter regulations and enforcement, including mandatory microchipping and desexing, and regulating cats similarly to dogs; the negative influence of social media; the importance of desexing to control populations and improve behaviour; increased risks to the roaming animals themselves, other animals, humans, and the environment; nuisance behaviours; and differing opinions on whether roaming cats or dogs are more of an issue. Conclusion: The findings align with previous research indicating a growing but inconsistent public awareness of animal welfare and environmental impacts associated with free-roaming cats. They highlight the need for education and targeted policy to address inconsistencies in attitudes and promote responsible cat ownership. Clinical relevance: Addressing these issues through enhanced public education and policy measures will help to balance animal welfare with community safety and environmental protection.Item Investigation of post-vaccinal canine distemper involving the Rockborn-like strain in nine puppies in New Zealand(Taylor and Francis Group on behalf of the New Zealand Veterinary Association, 2025-04-09) Gulliver E; Taylor H; Eames M; Chernyavtseva A; Jauregui R; Wilson A; Bestbier M; O’Connell J; Buckle K; Castillo-Alcala FCase history: This report details investigations into nine cases of neurological disease and/or sudden death in 8–13-week-old puppies between 2021 and 2024. Aside from two pairs of littermates, cases were unrelated. The puppies had an onset of clinical signs 9–23 days following at least one “on-label” dose of a commercially available quadrivalent vaccine containing live attenuated canine distemper virus (CDV). Clinical findings: Eight of the nine cases displayed signs typical of “classic distemper,” including seizures, circling, tremors, hypersalivation, progressive neurological deficits, pyrexia, and/or respiratory and gastrointestinal signs. Pathological and molecular investigations were undertaken in eight cases. Mononuclear/lymphohistiocytic encephalitis or meningoencephalitis with or without neuronal intranuclear inclusion bodies was present in seven cases. Five cases had bronchopneumonia. Other lesions included poliomyelitis, necrotising enteritis and myocardial necrosis or myocarditis. PCR for CDV was positive on tissues from seven cases, and immunohistochemistry for CDV was positive on neural tissues in six cases. Whole genome sequencing of PCR amplicons demonstrated a Rockborn-like strain with 99.9% homogeneity between samples from four cases and a vial of vaccine. Diagnosis: Based on the combination of case history, pathological findings, molecular test results and/or whole genome sequencing, a diagnosis of post-vaccinal canine distemper was confirmed in six cases and presumed in two. Clinical relevance: Outbreaks of canine distemper have been stemmed by widespread vaccination starting in the mid-twentieth century. Consequently, confirmed cases of natural CDV have not been reported in New Zealand since an outbreak in the 1980s, and CDV is considered a “notifiable organism” as per the Biosecurity Act 1993. This is the first case series to report genomic investigation of post-vaccinal canine distemper in New Zealand puppies and highlights a rare adverse event associated with routine vaccination. Our results suggest that puppies with neurological, respiratory and/or gastrointestinal disease with an onset within 6 weeks of vaccination with live attenuated CDV should be reported and investigated accordingly.Item Characteristics and challenges of companion animal rescue organisations in New Zealand.(Taylor and Francis Group, 2024-05-08) Roseveare C; Gates MCAIMS: To describe the characteristics of companion animal rescue organisations (CARO) in New Zealand; to describe current capacity, resource limitations and challenges of CARO with a particular focus on cats and dogs; and to explore support for creating a national database of CARO in New Zealand. METHODS: A cross-sectional survey was administered to CARO in New Zealand in May 2022. The survey asked about organisational characteristics, types and numbers of animals cared for, services provided, policies, staffing, funding sources, challenges, and attitudes towards a national database for rescue organisations. Descriptive statistics were provided for all quantitative study variables and free-text comments were analysed for common themes. RESULTS: The survey was completed by 106/208 (51%) known CARO distributed across the country. These CARO provided services to an estimated 59,874 homeless animals annually with 86/106 (81%) providing services to cats and/or dogs. Primary services provided by CARO who cared for cats or dogs included rehoming (72/86; 84%) and housing (70/86; 81%) animals. Intake was managed through a combination of strategies. Donations (72/86; 82%) were the main funding source. The 62 registered charities were more likely to report being funded by grants than the 23 non-charities (39/62 (63%) vs. 1/23 (4%); p < 0.001), and non-charities were more likely to self-fund (18/23 (78%) vs. 20/62 (32%); p < 0.001). Nearly half of the CARO that provided workforce information (35/72; 49%) had a workforce of 10 or fewer including volunteers. A total of 5,699 people worked for 86 CARO that care for cats or dogs of whom 4,847 (85%) were part-time volunteers. Of the 72 cat and dog CARO who provided workforce information, 57/72 (79%) relied solely on volunteers.The majority of all 106 CARO respondents (78/106; 73%) indicated they were likely to register on a national database of CARO, subject to addressing concerns about time required and information security.CARO respondents described challenges of insufficient funding, access to veterinary services, and a shortage of volunteers and foster homes, with additional concerns including a lack of public awareness, supportive legislation, and resources. Financial support (90/106; 85%) and policy change (76/106; 72%) were preferred support options. CONCLUSIONS: This study highlights the significant role played by CARO in New Zealand and the challenges they face, emphasising the need for financial support, legislation, and initiatives extending beyond the rescue sector to reduce the number of animals being surrendered. The findings also suggest a willingness among CARO to participate in a national database.Item A frameshift-deletion mutation in Reelin causes cerebellar hypoplasia in White Swiss Shepherd dogs(John Wiley & Sons Ltd on behalf of Stichting International Foundation for Animal Genetics, 2023-10) Littlejohn MD; Sneddon N; Dittmer K; Keehan M; Stephen M; Drögemüller M; Garrick DCerebellar hypoplasia is a heterogeneous neurological condition in which the cerebellum is smaller than usual or not completely developed. The condition can have genetic origins, with Mendelian-effect mutations described in several mammalian species. Here, we describe a genetic investigation of cerebellar hypoplasia in White Swiss Shepherd dogs, where two affected puppies were identified from a litter with a recent common ancestor on both sides of their pedigree. Whole genome sequencing was conducted for 10 dogs in this family, and filtering of these data based on a recessive transmission hypothesis highlighted five protein-altering candidate variants - including a frameshift-deletion of the Reelin (RELN) gene (p.Val947*). Given the status of RELN as a gene responsible for cerebellar hypoplasia in humans, sheep and mice, these data strongly suggest the loss-of-function variant as underlying these effects. This variant has not been found in other dog breeds nor in a cohort of European White Swiss Shepherds, suggesting a recent mutation event. This finding will support the genotyping of a more diverse sample of dogs, and should aid future management of the harmful allele through optimised mating schemes.Item Quality of Life Measurement in Dogs and Cats: A Scoping Review of Generic Tools(MDPI (Basel, Switzerland), 2022-02-08) Fulmer AE; Laven LJ; Hill KE; Paterson MQuality of life (QoL) assessment in companion animals is an essential aspect of veterinary medicine that helps guide treatment decisions and ensures optimal animal welfare. Veterinarians and pet owners can use disease-specific or generic QoL assessment tools to evaluate an individual animal's QoL. The aim of this scoping review was to identify and assess published generic QoL assessment tools suitable for use in either dogs or cats. A literature search identified 82 relevant publications, nine of which contained appropriate generic QoL assessment tools in accordance with inclusion and exclusion criteria. Each tool was assessed for evidence of psychometric evaluation including statistical analysis, reliability and validity. Commonly included items were determined to highlight potential important aspects of dog or cat QoL. Five of the nine publications used a statistical method such as factor analysis to determine tool design and structure. Although at least one aspect of reliability and validity was assessed for seven of the tools, none were validated across all measures. Two of the publications contained minimal to no statistical analysis. Common items for both dogs and cats included those regarding activity level, the desire for interaction and appetite. In addition, common items for cats included those regarding mood and grooming. This scoping review identified and evaluated currently available generic QoL assessment tools, providing a reference point for future tool development and validation.
