Neutering Pets

Female cats

Female cats will nearly always be routinely neutered. It is of course possible to let a female have a litter and then carry this out afterwards. However it should be remembered that it is not always possible to find homes for the kittens and there are often unwanted kittens and cats that need good homes. If female cats were left un-neutered they would continue having two litters a year for life.

Male cats

Male cats should also be routinely neutered to prevent their fighting and wandering tendencies which inevitably lead to either early death or injury by road accidents or from diseases contracted from their life style. Urine marking with its strong odour is also avoided.

Female dogs

Bitches are usually neutered to avoid the continued problem of their seasons which occur twice yearly and also to avoid 'false pregnancy' which often occurs 6-8 weeks after the season. Early neutering will significantly reduce the chances of mammary tumours later in life and of course avoid the occurrence of infection of the uterus (pyometra).

Male dogs

Male dogs are most often neutered to avoid behavioural problems such as aggression, wandering and urine marking.

Please do not hesitate to ask for advice on this subject if you have any concerns. The operations involved (castration and hysterectomy) require a general anaesthetic. Hysterectomy is of course a more major surgery and although occasional problems can be encountered the procedure is usually routinely straightforward.


We recommend neutering rabbits as soon as they become sexually mature at around 4-6 months of age.

Pet rabbits can be happier with a companion to live with but there may be problems such as fighting and unwanted litters. Neutering at a young age avoids these problems.

It has been shown that neutered rabbits live longer.

Unspayed females are likely to develop uterine or ovarian cancer by the age of 5 years. This is virtually eliminated by spaying.

Neutered males live longer and are less likely to be aggressive. They will be less stressed and friendlier companions. An aggressive rabbit can be quite frightening, especially to a small child.

Neutering will remove the urge to mate making your rabbit calmer and happier.

Rabbits spray urine to mark their territory and in some cases will do so over their owners as a sign of affection, especially in the breeding season. Once neutered, male rabbits will generally stop spraying urine.

Both males and females are easier to litter train once they have been neutered which can a big advantage if you want to keep your rabbit as a house pet.
