We have a black and white cat that is about 6 months old. She is very aggressive, she bites, she claws and she chews on just about anything. I've never seen a cat chew on things like this one and I've been around cats and kittens all my life. I think she is part puppy. She can be very nice and calm and suddenly attack but her nice and calm is rare. Her attacks are pretty vicious. Is there a chance that once we get her spayed (scheduled for April) she will get calmer? This is my daughers cat that she got after the death of her beloved calico cat (who was a sweet cat) We have had this cat since she was 7 weeks old and she just keeps getting meaner. Is there any hope?
