Castration (of male pets) and spaying (of female pets) can be done from 6 months old.

Male dogs

Un-castrated male dogs are more likely to be disobedient and also mount inappropriate objects such as your leg, cushions and even small children! Castration prevents tumours of the testicles and prostate problems in later life.

Female dogs

An adult female will come into season at least once every year, this can be quite disruptive for an owner as she will get a lot of unwanted attention from male dogs. Early neutering can prevent mammary tumours and womb infections that occur in later life; these conditions can be life threatening to your pet as well as resulting in costly surgical fees.

Male cats

Cats are territorial animals, and male cats will wander about their territory marking areas with foul smelling urine. The urine is passed as a ‘spraying jet’ up trees, bushes etc but may also include parts of your house - e.g. furniture, doors, beds etc! Having your male cat neutered can help to make him less territorial and therefore prevent spraying. Males will also wander in search of a mate often going missing for days or even weeks - he may get into fights with other males, causing wounds which may form into abcesses, or worse transmit serious viral infections such as feline AIDS. Wandering may also cause your male cat to be injured in a road traffic accident. Statistics show that of all the cats killed on roads, most are uncastrated males.

Female cats

During her season, you may notice your cat's behaviour changes - she may become very nervous and hide away or she may seek attention all the time. She may roll about on her back and yowl to advertise that she is in season, and she may even begin to spray her territory. This is all to attract a male and an unneutered female cat can reproduce at an alarming rate! A healthy female can breed from the age of 6 months with 5 or 6 kittens in a litter as many as 3 times a year! In five years, a single unneutered female could be responsible for 90 unwanted kittens of her own, and 20,000 descendants! Would you be prepared to try to find good homes for all these kittens?


Rabbits breed like, well, rabbits (as the saying goes); if left to breed unchecked a single pair could produce 20,000 decendants in five years - that's a lot of rabbits! Un-neutered male and female rabbits can be aggressive and less easy to handle than their neutered counterparts. Neutering female rabbits prevents tumours of the womb developing in later life.
