Our first (male) cat liked the new kitten when we brought her home, but he hated the new male stray cat we let in a few years later. The two never became friends, but after awhile they fought less and learned to tolerate each other. When the female died, we bought a Bengal kitten. She & the stray cat hit it off, but the original male cat hated her. She kept trying her hardest to be his friend and eventually they did become good buddies. When he died, she was devastated. We then bought a Tonkinese kitten, but he and the Bengal have had a never-ending hatred for each other. It's been 7 years now & they hate each other as much as ever. It's constant warfare in our home between the two. I'm glad your two cats are getting along better!
