Hi Guys: I breed Ragdoll and Himalayan kittens and have a female that has me totally stumped. This little girl is 2 1/2 years old and she had never had regular heats as my other ladies do. But went into heat a while ago. I took her to the breeders and she never observed any activity. However 6 weeks later she has not gone back into heat. Appears to have a "tummy" but even though her nipples appear larger they are definately not pink. Has anyone ever had a female where the nipples didn't go pink. This is her first litter.
