Our cat used to spend her time (most of the night, actually, to gauge from the noise) collecting erasers, pens, clothespegs, balls, hairbands, gidgets and gadgets and geegaws, oh, and her toys of course - batting them around the livingroom, chasing them down the stairs, and then finally herding them in under the (very low) chest of drawers in the downstairs hallway. Then she'd lose interest.

Every once in a while when we started to miss things we'd have to go down and lift up the chest of drawers to check her stash
