Neutering your cat

Neutering your cat is advisable for all except breeding animals. Even house cats will profit from the health benefits of neutering, and may be less likely to stray if given the opportunity.


A male kitten can become sexually aware from as young as six months old. They may start marking territory by spraying urine, and over time develop a characteristic “tom cat” smell.  An entire (un-neutered) male is more likely to wander, increasing risk of car accidents, and fight, often leading to cuts, abscesses and infections.  Fighting also spreads feline immunodeficiency virus. This is a deadly viral disease affecting cats, spread via bite wounds. Lastly, castration prevents testicular tumours.


Female kittens can come into season as young as six months old. Cats usually come into season between March and September, although this can vary.  During the breeding season an entire (un-neutered) female will come into heat every three weeks. This means she is receptive to mating; a fact she advertises by being extremely vocal. Cats in heat are often very afectionate, moreso than normal. They may also adopt a characteristic position known as “lordosis”. The cat crouches on her front legs holding her rear end in the air; this position is ready for mating. Spaying your female cat protects her from uterine cancers and infection of the uterus, called pyometra, which can be a very serious condition

Neutering practicalities

Neutering male and female cats is simple and quick when performed at a young age.  It is a slightly more invasive procedure for a female because the surgeon must enter the abdomen. This is usually done through the left body wall, leaving an incision upto a few centimetres in length. Neutering males is very simple.

At Springfield we neuter cats from four months of age. Ideally we wait until they are 2kg in bodyweight, to better cope with the anaesthetic, however in the case of siblings cohabiting or feral cats we will neuter them from four months irrespective of size.

Neutering is a day procedure, not requiring overnight hospitalisation. We recommend that cats stay in the house for upto ten days post surgery; the nurse will discuss post-op care with you on discharge.
