I have a ten year old male cat and nine months ago I got a female kitten. Mostly they ignore each other, but anytime my older cat gets near the kitten, my kitten hisses, meows, and runs off. She even claws at my cat. He doesn't even do anything to provoke it. He'll jump on the bed, and she will hiss and claw at him as she hurries to get off the bed. He just stands there very still and waits for her to be gone, then cuddles up next to me and starts cleaning himself like he does not care. She's violent toward him, and he just puts up with it. Is there anyway to get her to accept him? Especially since he was here first!

Figure it out. She is reacting normally to the dominant male who she knows instinctly is the boss by tenure. They have to find their own level, you let them work it out or separate them but you will only be delaying the process.
