NEUTERING

Why should I have my cat neutered?

Males

Neutering, or castration, offers a number of advantages, especially if performed at an early age (6-9 months). Following puberty, at approximately 8-9 months old, the male cat develops a number of often undesirable behavioural changes. He will become territorial and start to mark areas, often in the house, by spraying urine, which will by now have developed a particularly strong (and difficult to remove) odour. He will start to enlarge his territory by straying ever farther from the house, particularly at night. It is for this reason that many cats involved in road traffic accidents are non-neutered males. By increasing his territory he will come into contact with other cats and so fight for dominance. Inflicted fight wounds can result in severe infections and abscesses. Since diseases such as FIV and FeLV - which can cause AIDS like syndromes and cancers in cats, can be spread through bites it comes as no surprise to find that those cats most commonly affected by such incurable viruses are non-neutered tomcats. Finally, but not least, neutering prevents the siring of often unwanted litters.

The longer a tomcat is left to spray and fight, the less likely neutering will stop it.

Females

Neutering, or spaying, in female cats also offers several advantages. Most obviously, it will prevent the prospect of unplanned litters. Once puberty is reached, on average at around 7 months old, during most of the year the queen will be “calling” for approximately 1 week in every 2-3 until she is mated. During calling she may display unsociable behaviour, which is often manifest as loud and persistent crying, and frequent rubbing and rolling on the floor. Such behaviour and her scent will attract pestering tomcats from miles around. This will all be eliminated by neutering. Finally, spaying will remove the risk of uterine infection, and may reduce the future risk of breast cancer developing.

There is no medical reason for letting your cat have a litter before she is neutered.

When should I have my cat neutered?

In most cases, for the reasons stated above, it is desirable to neuter before puberty, and it is customary to operate on kittens at an early age. The actual age chosen will depend upon the preference of your veterinary surgeon - many individuals will neuter both male and female cats at around 5-6 months old, however some operate at 2-3 months of age.  Cats can be neutered at any age.  It is possible to neuter when pregnant.  Please contact the surgery for further details regarding our neutering policy.

What does the operation involve?

Both male and female cats will have to undergo a general anaesthetic. This will involve a period of starvation (usually overnight) before the operation, however most animals can return home on the day of surgery, providing they have fully recovered from the anaesthetic.

In male cats both of the testes are removed in their entirety through a small incision in the scrotum. Stitches are rarely required in the skin.

In female cats the operation is performed through a relatively small incision made either in the flank, or in the midline of the abdomen. Both ovaries are always removed along with the entire or majority of the uterus. Normally, skin stitches will be placed, which will be removed after around 10 days, unless absorbable material has been used.

What surgical complications could arise?

In general, complications are rare during neutering of kittens, however, as with all surgical procedures, there is always a small risk:-

Anaesthetic collapse

It is possible that any individual animal could have an untoward reaction following the administration of a drug. Such cases are impossible to predict, but are thankfully rare.

One potential danger arises from the cat not being starved correctly before being presented for anaesthesia. It is essential that all instructions to this effect are strictly followed.

In addition, any signs of ill health should be reported to your veterinary surgeon prior to an operation.

Internal haemorrhage

This can occur through a ligature slipping after the abdomen has been closed.

Post-operative infection

This may occur internally or around the incision wound. In most cases the infection can be controlled with antibiotics.

Sinus formation

Although rare, occasionally the body will react to certain types of suture material used during surgery. This results in a weeping wound which may even appear some weeks after surgery was performed. Often a further operation is required to remove the offending material.

What adverse affects might neutering have on my cat?

In the vast majority of cases no adverse affects are noted following neutering. However, some neutered animals have a tendency to put on excess weight by storing surplus fat. Such pets require a balanced diet and should not be over-fed.

In certain cats, notably Siamese, the hair that grows back over an operation site may be noticeably darker, due to a difference in the skin temperature. This darker patch may grow out with the following moult as the hair is replaced.
