A male kitten can become sexually aware from as young as six months old and he may start pungent marking of his territory.
Unless you want to breed from your cat, castration of a male cat is quite a minor operation if done early – usually at six months.
An un-neutered male is more likely to get involved in fights often resulting in absesses and other ailments. He is also more prone to catch Feline Immuno-deficiency virus – a deadly viral disease which is spread by bite wounds. Neutering your male cat also stops testicular tumours occurring.
Female kittens, as young as six months, can come into season.
Cats usually come into season between March and September, although this can vary.
During the breeding season an unspayed female – a Queen – will come onto heat every three weeks. When on heat, a female cat is usually extremely vocal. She is usually very affectionate, even more than normal. She may also adopt a characteristic position, called “lordosis”. In this stance, she crouches down on her front legs and holds her rear end up, in a position ready to mate.
As with males, unless you are planning to breed from your female, you can have her spayed from six months onwards – the sooner the better. Ask your veterinary surgeon for advice.
