I know that one of the signs of cats showing dominance over another cat is by mounting them and biting the back of their neck, but is it usual to see a kitten do this? This evening as we're watching Isis, the 11 week old kitten, play with Mischief, my almost two year old cat, we witnessed her several times jump on her back and mount her biting Mischief's neck. At first I thought that it might just have been just playing, but staying on Mischief's back is not easy for Isis who is quite a bit smaller then Mischief. But she wouldn't give up. She jump on her back, slip off, jump back on her back, and slip off again. Mischief just laid there wagging her tail back and forth.
