Every breeder who is a member here would advocate that, not only should you do your own research before engaging in breeding, but you should also have a mentor -- an experienced breeder -- to help you along the way. I hope the person you bought Kitoko from is willing to mentor you. Breeding is, imho, hard work and there's more involved than just putting a fertile female and male together and letting nature take its course.
Some breeds can go into their first heat at 4 months; others take longer, around 10 months of age. It's possible that your baby's hormones are gearing up. Since I'm not a breeder, I can't give any advice or insight in this area.
Some things I would ask Kit's breeder is what do you do to help her go through her heat cycles until she is old enough to breed; what type of housing should you have for her during her cycles; what type of behavior can you expect from her during each phase of her cycles. How old should she be before she has her first litter?
Also, who will she mate with? Some breeders will not loan out their males. Are you planning on purchasing a breeding male? If not, from whom will you acquire stud services.
