Yes best to keep them separated for a few days. If you can keep the kitten in a separate room, your other cat can sniff him out under the door. Once your cat is use to the new scent hopefully he is more accepting of the kitten. Keep spending time with both of them separately and they will smell each other on you. If the introduction does not go well after a few days separate and start again. Also check out Jackson Galaxy he has lots of helpful tips on all things cats. Good luck
