Feline obesity affects over 50% of cats in some surveys, causing or contributing to diabetes, arthritis, urinary disease, and reduced lifespan — representing one of the most common and preventable welfare problems.
Cat obesity causes chronic welfare impairment through multiple pathways. Obese cats groom less effectively, develop dirty, matted coats, and may be unable to reach their hindquarters — reducing hygiene and causing discomfort. Arthritic pain from excess joint load limits mobility and normal feline behaviours. Diabetes development causes polyuria, polydipsia, and neuropathy. The cat cannot understand or accept dietary restriction, creating frustration when food is limited — welfare-sensitive weight loss programs use puzzle feeders and multiple small meals to satisfy feeding motivation while reducing caloric intake. Owners often interpret food-seeking behaviour as hunger and respond by overfeeding, creating a cycle of enabling that requires clear veterinary guidance to break.
