Julie used to eat the tails and bat the mouse around for kicks...until the dog discovered them and decided to eat them and then bringing them back up. ewwww!
Here favorite is pompom balls...especially the ones with the glittery mylar threads in them. We play this game daily...she bats them under the microwave or computer stand and I dig them out. There are at least a dozen of them MIA. They seem to show up on cleaning day.
