I have blues that do fine. I have one now that is mothering hers and another litter that is about a week older, because their black and white momma wont take care of them. I had a siamese that bred ok, but was a complete monster when she had babies. Would come flying out of anywhere to bite the crap out of you. I fed her off. One of her sons just threw me a siamese female. I'm gonna hang onto her and see what happens.
