Hi, so back in April we rescued an 8 week old kitten. We expected that our 10 year old cat would not like her but we never dreamed it would be this bad. We introduced them slowly, separated them and switched their rooms so they could smell each other scents. None of that worked, and our 10 year old cat tries to kill the kitten every chance she gets. They cannot be in the same room together and when they are apart, the 10 year old bangs her head on the door trying to get ahold of the kitten. It is very frightening because if they ever got in the same room while we were away, we believe she would kill her. Any ideas how we can get the 10 year old to like our new kitten? Thanks in advance!
