I took in a two-year-old cat from a friend that was moving and could not take him. I already have three cats. He gets along with two of them, but not the third. He stalks her to scare her, and then goes after her. She hisses and growls and runs to hide. I don't think he intends to hurt her; I think that he thinks it is a game. This has been going on for almost a year. What can I do?
I would give the 3rd cat a break sometimes. Either put the newer cat in a room or give her a place where she can go and sleep and relax. Some cats will barely tolerate each other, and some get along relatively quickly without much fuss. You can also try giving them both a treat in each other's presence or a bit of canned food. Make every time they are together something pleasurable from you, and it might cut down on the behavior.
