I have two kittens they are both 15 weeks old one is a boy and the other a girl. They are brother and sister. My question is how old do they have to be to have kittens. I ask this because the male is licking and sniffing where he shouldn't. I haven't seen him try anything but I was just curious. They will be fixed at 18 weeks. Am I pushing it too far?
The female can go into heat anytime after 6 mo of age. vetcare
