I just bought a trash can w/a lock on it, believe it or not. It's to prevent pets and kids from getting into the trash. I can't for the life of me recall the name brand and I just now looked to see if the name is on it anywhere but it isn't. I got it at Bed Bath and Beyond, though, and I'm sure you'll see them there. It has wheels on the back and a soft close lid, which I also like a lot. When you step on the pedal for the lid to go up, it closes softly. Then you can lock it at night to keep Duck out of it. (It's just a slide lock, nothing complicated.)
