Lovely kittens!. I truely recommend to choose a female cat than a male for many reasons:
* They are more intelligent.
* They are not so noisy when the mating time come. You know, the male cats are just annoying when that time comes.
* They are best hunters.
* They are more nobles and more social.
If you choose a female cat I sugget you let her have one time kittens, and then operate her, and everything will be just fine.
