Are dogs and cats behavior adversely affected by sterilization?
The only changes in dog and cat behavior after spaying or neutering are positive changes. Male cats tend to reduce territorial spraying, depending on their age at neutering. Neutered dogs and cats fight less, resulting in fewer bite and scratch wounds and lessening the spread of contagious diseases. Male dogs and cats tend to stay home more after neutering because they no longer wander in search of a mate.
