I have a kitten who is 6months old and my brother just got a dog who just turned 5months old yesterday. The puppy is locked up with my brother in his room because he was neutered before we got him so the kitten and puppy haven't exactly met yet. Although, on the day that we got him, my kitten slipped into my brothers room and hid under his bed. When I tried to retrieve him I saw him see a part of the puppy back and he hissed, and started creeping towards him. When I pulled him out from under the bed he hissed at me. He didn't try to attack me or anything though. Now I'm afraid to see how they will react to each other when they actually meet for real when the puppy recovers...How do I make it to where my kitten will not hiss at the puppy again? What do I do?
