I have a four month old Siamese kitten girl named Lily. We got her two months ago and her breeder told us she was a girl but ever since we got her i have not been sure. Should females have any sort of bulge back there, or should it be complatly flat. I also have her two year old brother and she looks alot like him in her genitals (hes been neutered). So i was wondering what you guys think. Photos would be helpful. siamese color cats would also help because there genitals are a different color than the surronding area.
