First off, I'd like to say that the cat is dead. She died about 5 years ago. So anyway, we had a cat. She was left at the door of the church in the winter, so we do not know where she came from. She had a particularly interesting perk ( although sadly, I only now realize how important of a discovery it COULD have been.). Of about 7 times that she had kittens, all of them were female. She always had 3 kittens at a time, so that would make 21 females in total, 2 of which we kept, neither seemed to have the perk. I also understand that it could have been a lucky streak, but I was wondering what could cause only female kittens and how much of an impact this could have made.
