A recent study published in Vet Record found that neutering cats at four months old does not increase their risk of developing weight problems compared to neutering at six months. Analyzing over 2,000 clinical records from the University of Bristol’s Bristol Cats study, researchers found no significant difference in body condition score (BCS) or bodyweight as cats aged. The study revealed that male cats generally had higher bodyweight and BCS than females, with seasonal fluctuations affecting females more. Hair length influenced BCS assessments but not actual weight, highlighting the importance of using both metrics in Veterinary evaluations.
These findings support early neutering as a safe, effective strategy for preventing unwanted litters and managing cat overpopulation without compromising feline welfare. Experts from Cats Protection and Bristol Veterinary School emphasized the value of this data in guiding clinical decisions and reducing unplanned litters, especially during times of financial and resource constraints.
