Naughtius Maximus Numero Trois

Almost every time I come into the house from the garage, Tommy is waiting there trying to get out. He often succeeds. He probably spends a lot of time outdoors every day. We try to limit his outside play, though, mostly because of the unfortunate episode from his past when he stayed out for about 36 hours and scared everyone.
He's pretty good about coming back though. We often leave the garage door slightly up for him and often find him waiting on top of one of the cars for us to let him in the house.
Nearly once a week he will return from his romp in the neighborhood without his collar. We know he gets into scraps with other cats. I imagine some neighborhood bully cat with a series of cat collars painted on the side of his litter box.
When he was young he would climb the canopy of our bed a lot. At a certain age, or perhaps a certain body size, he stopped doing it. However, now that young Digory is around and climbing the canopy, Tommy has taken to it again. It is funny to see them tightrope walk the rails with their tails whipping around like a propeller.
They will often just perch near a cross member where they can balance more easily with three paws on one axis and a fourth on another. I have fun teasing them when they are in that position. I touch tap them on the fourth, outboard paw. They can't just pick it up because they would lose their balance. They try to swipe at my hand. But, they aren't very well poised to do that either.
A couple of times Digory has jumped from the canopy to the top of the bookcase. The other night he spent most of the night sleeping in a basket on top of the bookcase.
