I have a 5 year old cat that is very loving and cuddley. About 8 weeks ago I got a new kitten, he's a lovely ginger Tom. Two weeks ago he neutered, the vet said it would calm him down but it hasn't. He is so aggressive towards my older cat, he bites him pulls his fur out and basically rules the roost. My older cat just wants to be left alone and sleep in his chair in the garden but Burt has even taken that over. He is only about 21 weeks old and I know he will very playful but will he ever stop being vicious towards my older cat Eddie!? PLEASE HELP!
