DMC, if it makes you feel more comfortable about Spuds...when we got our 2 indoor kittens, DH got 3 others to keep at the golf course. He kept them in the office the first several months then installed a cat door so they could go in or out. Now that those 3 are about 6 months old, they spend the majority of their time outside chasing down mice and voles. Terrific mousers, the population of them has dramatically declined. The cats are friendly too having been inside long enough to get used to people. They can use their cat door to go inside to get out of the weather (or hide) but do almost all their "business" outside (so very little litter box cleaning needed) and they enjoy climbing the trees, hanging out on the courtyard in front of the pro shop and riding around on DH's golf cart. We know that some day they'll probably have a coyote encounter but that's part of having an outside cat.
Here they (Big Daddy, PeeWee and Jet) are with my oldest DS when he came for a visit earlier this fall:
