Knowledge, attitudes and practices regarding the environmental implications of pet ownership in Hong Kong

This study aimed to describe the knowledge, attitudes, and practices (KAPs) of cat and dog owners in Hong Kong regarding the environmental implications of their pets. An online questionnaire-based survey was distributed through various veterinary clinics and social media platforms in Hong Kong, targeting all adult companion cat and/or dog guardians. Of 276 respondents, 224 completed the survey. Most participants (78%) purchased pet toys more than once a year. Store-bought dry food, along with store-bought wet food, were the most popular food choices; no respondent considered environmental aspects or sustainability issues when purchasing pet food, with the main reason being ‘never having heard of such options’ (35.6%). Flushing litter into the toilet and regular trash bin disposal were reported by 48.1% and 34.8% of pet owners, while composting was rare (0.4%). Biodegradable and regular plastic waste bags were used by 43.8% and 33.8% of dog owners, respectively. While awareness of designated public pet waste bins was highest (91%), most respondents had never heard of the environmental footprint of pet food or the biodiversity implications of free-roaming pets. Targeted interventions, such as developing user-friendly educational resources and involving veterinarians, are recommended to encourage environmentally responsible pet care and advance urban sustainability.
