I thought about that .... problem is, he won't do it on command.  I wouldn't have know he was doing it, except I kind of surprised him in the act.  I knew someone was doing it ... and I knew it wasn't me, but I didn't know which cat, until I caught little Kevin red pawed.

It's kind of cool to watch ... he puts one paw across the back of the can, then takes the other paw and pushes the ring up.  Then he takes his claws and hooks them on the ring and pulls back.  And viola ... open can.

I'm not certain how he is getting the pantry door open, but I've purchased some of those old hook and ring gate latches to stick on all doors and cabinet doors.  And, I am putting them out of his reach.  Of course, if he learns how to move and use the step ladder, I'm doomed.

Could be worse, could be raining.
