Do cats change when they get neutered?

Answered by Douglas Hiatt

When it comes to the question of whether cats change when they get neutered, it is important to understand the specific behaviors that may be influenced by the removal of male hormones. Neutering, or castration, involves the removal of a male cat’s testicles, which are responsible for producing testosterone. This procedure is typically done to prevent unwanted pregnancies and reduce certain behaviors associated with intact male cats.

One of the primary effects of neutering is the reduction of sexually dimorphic behaviors in male cats. These behaviors are influenced by male hormones and are typically related to mating and territoriality. For example, intact male cats often display more aggressive behavior, especially towards other male cats, as they compete for mates and defend their territory. Neutering can help reduce this aggression, making the cat more amiable and less likely to engage in fights.

Another behavior affected by neutering is roaming or wandering. Intact male cats tend to have a strong desire to search for mates and may roam far from home in search of a female in heat. This behavior can be dangerous as it increases the risk of accidents and exposure to diseases. Neutering can significantly decrease these roaming tendencies, helping to keep the cat safer and closer to home.

Additionally, neutering can reduce spraying or marking behavior in male cats. Intact males often mark their territory with urine, which has a strong and pungent odor. This behavior is a way for them to communicate their presence and attract potential mates. By removing the source of male hormones, neutering can help reduce or eliminate spraying behavior in most cases, making the cat more pleasant to live with.

It is important to note that not all behaviors in cats are influenced by male hormones, and therefore may not be affected by neutering. Temperament, training, and personality, for example, are primarily influenced by genetics and early upbringing rather than hormonal factors. Neutering does not change a cat’s fundamental personality traits or intelligence. Therefore, if a cat is docile and friendly before neutering, it will likely remain so after the procedure.

Personal experiences with neutering cats have shown that the overall effect of the procedure is often positive. Male cats tend to become more relaxed and less focused on mating-related behaviors. They may become more affectionate and less prone to aggression or territorial disputes. Additionally, neutering can have health benefits, such as reducing the risk of certain reproductive cancers.

While neutering can have a significant impact on sexually dimorphic behaviors in male cats, it does not fundamentally change a cat’s temperament, training, or personality. It is a responsible decision to have a cat neutered to prevent unwanted litters and reduce certain behavioral issues associated with intact males. However, it is important to remember that each cat is an individual, and the effects of neutering may vary. Consulting with a veterinarian can provide more specific information about the potential effects of neutering on an individual cat.
