I have a 6 1/2 cat and a 10 month kitten. My cat hisses whenever he sees the kitten. I don't see the cat very often. He doesn't like it at home so he hangs around the neighbourhood instead. I manage to get him home everyday for some food but the kitten always walks along. My cat then hisses and attacks my kitten. What can I do to get my cat to like the kitten?
