Prevalence and factors associated with overweight and obesity in cats in veterinary hospitals in France during the COVID-19 pandemic.

Abstract

Objectives: The present study aimed to determine the evolution of the percentage of overweight and obese cats during the COVID-19 pandemic in France, and to identify factors associated with excess weight to inform the development of targeted prevention strategies.

Methods: Cat owners visiting the veterinary hospitals of Maisons-Alfort and Toulouse between 2020 and 2022 for their pets' vaccinations were invited to answer a comprehensive questionnaire to gather general information about themselves and their cat, including details of its lifestyle, activity and diet. Only healthy adult cats were included in the study. During the vaccination consultation, veterinarians recorded the body condition score, muscle condition score and weight of each cat. This study followed a protocol adapted from a French study conducted in 2006 to allow analysis of any changes over time.

Results: Of the 274 cats included in the study, 9.1% were underweight, 43.4% had an ideal body condition and 47.5% were overweight. Factors positively linked to overweight included age, being crossbred, being a male and having an owner who underestimated the cat's body condition. Living with a child and having a high activity score as rated by the owner were associated with ideal body condition. The prevalence of cats with a sedentary lifestyle and the number of overweight cats had both increased since the previous study in 2006. Additionally, changes in cats' diets and lifestyles over time, including those influenced by the COVID-19 pandemic, have led to an increase in exclusive dry food consumption compared with the 2006 study.

Conclusions and relevance: Important changes in cats' diet and lifestyle occurred between 2006 and 2020-2022. This study emphasises the need for further investigation into the duration of the impacts of the COVID-19 pandemic on feline wellbeing. Educating owners on their cat's body condition and encouraging cats to be active can be effective strategies for maintaining feline health in response to ongoing global changes.
