Wow! I knew you would be a fountain of info! My plan was to keep him kenneled during the day and very slowly let him out and about only when we were home. I guess I thought he would always stay in the kennel but I may be very wrong! I have no rooms that I can block off strictly for him. I have a very old house and one room leads off of others so we and the other cats need access with no doors closed. I could use a small gate I suppose and the others could jump over it. That would keep him confined to a few small rooms until he was ready to move on. He would have to be kenneled for some time in the beginning to get everyone used to each other and then I guess it would be just one step at a time after that. HMMMM, lots to think about!
Thank you so very much for all the tips and advice. I'm going to have to really start checking into this.
Got to get by hubby first!! Wish me luck!!!

btw-He is extremely gentle, kind and very very loving! He follows your voice and lays his head up to the cage to be petted. I picked him up for the first time and he held on really tight but enjoyed being held. I understood his fear of being dropped so I made sure I held him securely. He is a true sweetheart but I don't know how he will do with other cats. He is alone in a cage so I don't know how that would go but his personality shows no signs of aggression. I'm guessing that it would be like introducing any other cat...hold your breath and pray for the best!
