Spaying and Neutering Cats for Welfare

Neutering cats prevents unwanted reproduction, reduces disease risk, and improves individual and population welfare.

Key Facts

UK cat rescue organisations receive approximately 400,000 unwanted cats annually
Unneutered female cats can have 3 litters of 4-5 kittens per year
Pyometra (uterine infection) affects 25% of unneutered female cats and is life-threatening
Neutering eliminates the welfare costs of pregnancy, birth, and kitten rearing in unplanned circumstances
Feral cat populations are controlled most effectively through TNR programs using neutering

Welfare Considerations

Cat neutering is one of the most impactful individual welfare interventions available. For female cats, neutering prevents repeated pregnancies which carry significant welfare costs — particularly for feral or inadequately cared for animals — and eliminates the risk of life-threatening pyometra. For male cats, neutering reduces roaming behaviour, fighting wounds, and the risk of FIV transmission through bite wounds. Population-level, widespread neutering is the most effective and humane approach to controlling unwanted cat populations.

Adopt neutered cats from rescue organisations rather than buying unneutered kittens
Support low-cost neutering schemes that improve access for owners who cannot afford standard fees
Advocate for neutering as a core component of feral cat TNR management
