 I didn't know that male kittens played rougher than female kittens. I've had litters of kittens, and they all seem to be rough and tumble and bite. Yeah, if there's just one or two males in there, they all kind of play the same game. But if it's an all-female litter, and as I say, they're quite uncommon just by chance. But three or four female kittens altogether, those people who've had them and had their behavior looked at, and they're really very, very soft animals.
