I've had my cat since it was a kitten. He is strictly indoor and has never been around other cats. He's now 7 years old. I've also befriended a stray and been feeding her for the last 2½ years and she decided to make my patio her home. They've never met except through the window and my cat isn't thrilled with her.
Now I'm moving to a house in a busier neighborhood. Should I take her and try to introduce them? Would it be OK to keep her as indoors as well? She's tried to come in, but I know my indoor cat would be upset. What should I do with her?
