My sister has a 5 month old kitten, and Remi loves to stalk and chase her. He has never bitten her, but he mouths at her. She will play for a while then get rough with her, like pens her down on the floor. My sister thinks their 'fighting' but Remi just wants to play. The hardest thing to deal with is that the kitten will come up to him and smack him, or walk very slowly by him when he is laying down. And she will not let him play with his toys. But as soon as Remi wants to play she freask out and hisses and doesn't want him around her. But no matter who starts its always Remi's fault. My sister said If I don't teach "my stupid mutt some manners" I can't bring him to her house anymore, and I stay at her house alot. I've tried teaching him "leave it" with kitten but he doesn't listen. Is there anything I can try to teach him to ignore the cat even if she starts the 'Fight.'
