They're not even that cuddly yet. They'll hiss if one is on the bed and the other hops up, and usually one has to slink away tail between her legs, or else they will get into a smacking fight with hissing and spitting and growling. But it is LESS violent than it used to be. I doubt they'll ever cuddle, but it's progressing.

I think it's because they were both the dominant cat. Sassy has been here longer, but Peach was 5 or 6 when we adopted her and was probably the dominate or single cat where she used to live. So both want to be the alpha, so to speak. Fortunately, when they start going at it, I make it known that actually I am the alpha and they need to cut it out. But they still bicker. Sigh.
