One cat is declawed but we do let him out during the day. He mostly sits on the deck and meows loudly to be let back inside. He's an older cat, so I don't want him to be outside too long, but like I said, he mostly sits or lays on the deck and basks in the sun.
The other cat is the Great Hunter and spends hours crouched over the mounds of dirt that the moles push up. I make him come in at night, we live on an acre in a semi-rural area just outside of town. I know there's squirrels, skunks, raccoons and maybe (probably) coyotes, plus lots of dogs, so I don't want him outside after dark. Our lot is wooded in the back, so there's plenty to keep a cat happy and the farthest he goes is next door, where they're happy to allow him to catch moles in their lawn too.
