Better Than a Hamster Ball

My son's pet hamster loved to be in his hamster ball, but it was hard to open and close. It broke easily, was expensive, and was small enough to get lost under furniture. We had a big plastic barrel from pretzels. We punched holes in the cap and the bottom. It is easier to unscrew the top, put him in, screw the top back on so he runs around the floor. He loves it.
