Daily gabapentin improved behavior modification progress and decreased stress in shelter cats from hoarding environments in a double-blind randomized placebo-controlled clinical trial.

OBJECTIVE: To evaluate the impact of daily gabapentin on behavior modification progression and signs of stress in fearful shelter cats from hoarding environments. ANIMALS: 37 cats (32 met inclusion criteria). PROCEDURES: Healthy fearful cats were entered into group (1) gabapentin or (2) placebo upon intake. Both groups received daily behavior modification. Cats received 10 mg/kg of liquid gabapentin or placebo every 12 hours. Daily measures of cat stress score, latency to emerge from hiding, general in-shelter behavior, and urine suppression were collected. Results were analyzed on an intention-to-treat and per-protocol basis (including only cats that received > 75% of their doses). Post-adoption surveys assessed cat social behavior. RESULTS: Of 32 fearful cats, 28 (87.5%) graduated from the behavior modification program in a median of 11 days (range, 4 to 51 days). Per-protocol analysis showed that gabapentin predicted quicker behavior modification progression and lower cat stress score, latency to emerge, and urine suppression compared to placebo. Median time to graduation was reduced by half with gabapentin. Intention-to-treat analysis showed that gabapentin predicted a lower cat stress score and latency to emerge. No differences were observed between groups for general in-shelter behavior. Among limited survey respondents (n = 7), despite showing unsocial behavior in the first week and among unfamiliar people, cats showed social behavior 1 year post-adoption. CLINICAL RELEVANCE: Daily gabapentin was beneficial in behavior modification progress and reduced signs of stress in shelter cats. Fearful cats from hoarding environments can be successfully treated with behavior modification ± daily gabapentin within an animal shelter.

Consumer attitudes toward bacteriophage applications to pet food.

This study used a two-part questionnaire to investigate consumer knowledge and attitudes toward bacteriophage applications in pet food, pet food safety, and environmental sustainability. Part 1 included questions about pet food safety, sustainability, and knowledge and attitudes toward bacteriophages. Next, participants reviewed educational materials about each, and Part 2 assessed if this increased knowledge of, or changed attitudes toward, bacteriophage application. Participants (n = 80), were recruited through Amazon Mechanical Turk (MT) (n = 45) and Social Media (SM) (n = 35). Mean responses in Part 1 and Part 2 were compared by paired t-tests, and mean responses between MT and SM were compared by t-tests. Participants reported pet food safety was important to them (combined proportion strongly agree or agree, mean ± SD) (75/80, 94%, MT 4.66 ± 0.60, SM 4.71 ± 0.95) and were most concerned with raw pet food safety (51/80, 64%, MT 3.88 ± 0.80, SM 3.17 ± 1.40). Participants rated environmental sustainability as important (61/80, 76%, MT 3.86 ± 0.94, SM 3.97 ± 0.66); however, it was not a strong driver of pet food purchasing (26/80, 33%, MT 3.31 ± 1.25, SM 2.82 ± 0.82). Overall, data showed an increase in knowledge of bacteriophages following a review of educational material. However, in the SM group, no statistically significant difference was observed in the comfort eating food with bacteriophage additives (SM Part 1 3.37 ± 1.05, SM Part 2 3.48 ± 1.12, p = 0.279), whereas the MT group did show an increase (MT Part 1 3.57 ± 1.01, MT Part 2 4.08 ± 0.92, p < 0.001). In the SM group, no statistically significant difference was observed in comfort feeding their pet food with bacteriophage additives (SM Part 1 3.40 ± 1.03, SM Part 2 3.45 ± 1.14, p = 0.571), whereas the MT group did show an increase (MT Part 1 3.57 ± 0.98, MT Part 2 4.31 ± 0.84, p < 0.001). The strongest objections related to safety concerns (20/53, 38%, MT 2.83 ± 0.96, SM 3.27 ± 0.84). These results demonstrate that despite increasing knowledge, there is still hesitancy among some consumers toward bacteriophage applications in pet food.

Reasons for Guardian-Relinquishment of Dogs to Shelters: Animal and Regional Predictors in British Columbia, Canada.

Dogs are relinquished to animal shelters for animal-related or guardian-related reasons. Understanding what drives relinquishment patterns is essential for informing intervention opportunities to keep animals with their guardians. Whereas, overall reasons for relinquishment in a given shelter system have been well explored, analysis of human and animal predictors of relinquishing for a specific reason has not been previously attempted. We used characteristics of relinquishment including year, population of the relinquishing guardian's region, health status of the dog, breed, age group, weight, and sex to predict reasons for dog relinquishment to British Columbia (BC) Society for the Prevention of Cruelty to Animals (SPCA) shelters across BC between 2008 and 2019 (n = 32,081). Relinquishment trends for puppies and adult dogs were also viewed and described. From 2008-2019, the proportion of dogs relinquished relative to total intake remained consistent (range: 31-35%). Primary reasons reported by guardians were having too many dogs (19%), housing issues (17%), personal issues (15%), financial issues (10%), dog behavior (10%), and guardian health (8%). Over years, an increasing proportion of dogs were relinquished for the reason "too many" (OR = 1.16, 95% CI, 1.10-1.23, p < 0.001) and "behavior" (OR = 1.34, 95% CI, 1.26-1.43, p < 0.001), while a decreasing proportion were relinquished due to financial problems (OR = 0.94, 95% CI, 0.88-1.00, p = 0.047). Being a puppy, mixed breed, small, and from a small or medium population center predicted the reason "too many." Being a senior, Healthy, or from a medium or large population center predicted the reason "housing issues." Being a non-puppy, Healthy dog in a large population center predicted the reason "personal issues." Being a puppy, non-Healthy, female, and from a large population center predicted the reason "financial issues." Being a larger young adult or adult and Healthy predicted the reason "dog behavior." Being an adult or senior small dog from a small population center predicted the reason "guardian health." Particularly promising region-specific intervention opportunities include efforts to prevent too many animals in small population centers, improvement of pet-inclusive housing in large population centers, and providing animal care support in large population centers. Accessible veterinary services, including low-cost or subsidized care, likely benefit dog retention across BC.

Climate Change and Companion Animals: Identifying Links and Opportunities for Mitigation and Adaptation Strategies.

Recent natural disasters and weather extremes are a stark reminder that we live in a climate crisis. Climate scientists and policymakers have asked each discipline to anticipate and create mitigation and adaptation plans in preparation for a worsening future. Companion animals both impact and are impacted by the changing climate through their intrinsically linked relationships to human society. In this theoretical paper, we argue that companion animal scientists are well-suited to address climate change issues. We identify several anticipated climate change outcomes, such as an increase in extreme weather events, human migration, disasters, and an increase in human inequity, and connect these outcomes to identified or hypothesized impacts on companion animals and the human-animal bond. We suggest opportunities to reduce climate change impacts on companion animals that include alterations to owner caretaking behaviors and breeding practices, and education of owners and governments on zoonosis and disaster preparedness. Furthermore, building climate resilience through decreasing inequity in companion animal fields is paramount; and we propose that a starting place can be in animal sheltering and other support services. We also summarize how companion animals and owners' caretaking behaviors are impacting climate change through the use of finite natural resources as well as pollution and carbon emissions. We propose that replacement, reduction, and refinement, that guide laboratory animal research, can also be useful to mitigate the effects of companion animals on the environment. We suggest criteria for successful mitigation and adaptation plans to include equitability, sustainability, respect for animals, and measurability. Finally, we end on a call to all companion animal professionals to actively consider their role in mitigating the impact of companion animals on the climate and preparing for the fallout of climate change in their communities.
