HowieDawn.....Bobby did what I did pretty much. I let them smell each other under the door and only let them be together with extreme supervision in the beginning. I also sort of had my new kitty quarantined because the vet said until he was tested for feline leukemia I should not mix them. By the time he was tested a couple of weeks had gone by, and by then my older cat knew he was "around" even though not within reach. Their first meeting was scary. My older one hissed (I had never heard him hiss before!!) The kitten ran under the nearest piece of furniture. Gradually he got brave. It was me who was the wimp!! My heart was in my mouth!! They are great together now. It seems that cat #1 is the boss though. I don't mean he is bossy to my other kitty, but I find that the second cat follows him around and will lay down next to him for a nap more than the other way around. Good luck with your new addition. With kitties it's hard to know when to stop adopting!!
