Back to the question " do you keep your cat in the garage?". Not on purpose. But there have been a few times that we've accidentally locked one of them in the garage and not noticed until the next morning.

Just last weekend, we were wondering where Joxer was, so I went to the garage and called, and herd a most pitiful meow from the attic. He had climbed up the ladder to the attic when we weren't looking, and we then closed the attic door (its one of those pull-down ladders), and locked him in there.

He's much better now, and we're being careful not to leave it unattended.
