Our cats kittens are six weeks old and are , as I expected, very feisty, playfull little cats. My problem is that mummy cat seems to behaving oddly, she is always miowing and keeps sitting at my feet looking as though she wants something. Even when I feed her she's not very happy. She seems depressed and she used to be a very content little cat. Any ideas?:( I feel really sorry for her. Xxxx
