He would become an outside cat for me...even if declawed they survive very well. I have been a cat (many at times-we have at least 10 now) owner all my life. We have had inside cats and outside cats. I am a firm believer of outside cats now. I am getting too old to enjoy all the cleanup and hair that they leave while being inside. Believe me, an inside cat adjusts very quickly to being an outside cat - especially if you have other outside cats. They know who feeds them - and where to go to get that food - and where to go to sleep. Good luck!
