If you are not planning to breed from your pet you should consider having them neutered. You should discuss the benefits and other considerations with your own vet. If female cats are roaming outside they will get pregnant if they are not neutered and entire tom cats can be a nuisance to others and are more likely to get into fights than neutered males. If you do decide to breed from your cat you should also seek advice from your vet. Most cats have kittens without any problems but it is important to be prepared in case things do go wrong.
