Desexing your cat.
If your kitten does not come to you already desexed, it is important that you take him/her to a trusted vet before the kitten is 6 months old. Vets will charge less for a young kitten (as a rough guide, approximately $60, as opposed to $120 upwards), so do not leave it until the cat is almost grown.
Benefits of having your female kitten desexed
In just 7 years, one female cat and her offspring can produce 420,000 cats!
There is no benefit to your cat to allow her to have a litter. It does not make her more placid or a happier cat. Breeding only adds to the unwanted cat population. If you want your children to "experience birth", buy them a couple of fish or mice, or better still hire a video/DVD from the library!
The spay operation involves removing the entire uterus and both ovaries via a tiny abdominal incision. The kitten will often be up and playing the same evening and sometimes, if sutures are placed to stitch the opening, there is no need for the cat to be returned to the vet to have these removed - check with your vet whether he needs you to return the cat to him.
Advantages of spaying your female kitten
No unwanted kittens to find homes for, involving cost of advertising, friends/relatives sometimes changing their minds and wanting to return the cat when older, and even having to keep the kitten yourself or having it put to sleep or surrendered to a shelter.
Advantages of having your male kitten desexed
Leave breeding to registered and experienced breeders. Very few of them make any money out of cat breeding!
