If you have no plans to breed from your cat then there are proven advantages to having him/her neutered, aside from reducing the number of unwanted kittens that need homes. Both toms and queens are usually neutered between 6-8 months of age but the operation can be carried out later.
In males, neutering reduces the tendency to roam and get into fights over territory. This reduces the risks of injury and of infectious diseases such as feline 'AIDS' and feline leukaemia. Castrating toms also decreases their tendency to spray urine.
In females, neutering reduces the incidence of diseases of the genital tract in later life, eliminates sexual behaviour and, again, removes the possibility of unplanned pregnancies.
What does it involve?
In males the surgery is called castration and involves removing the testicles. In females the surgery is called spaying and involves removing the ovaries and uterus.
In both cases the surgery is usually carried out as a day case. That is, leave your cat with your vet in the morning and collect him/her again that evening. In many cases if your cat has been spayed she will have non-dissolvable skin stitches which will need to be removed by your vet around ten days after the operation.
