For his safety, you might want to keep your kitty strictly indoors. http://pets.webmd.com/cats/features/should-you-have-an-indoor-cat-or-an-outdoor-catAm I being really unrealistic when I'm thinking cat don't destroy or are unclean, I really fear that they do. He is initially going to be an indoor cat & im then going to try him outside, but I'm not going to force him. He'll be left about 14hrs a day including sleeping time. With his cat trees & toys do you think he'll be ok??
Your kitty will likely nap for most of the time that you're gone.
