I discovered that a mouse (wild one) had visited my pony room, and ruined a stickle.
When my hamster got out, he did a bit of carnage. I didn't find it until we moved, but he chewed all the yarn hair off my G3 plush (buzzed it as high as he could reach, so her tail was a perfect one inch long bob). I found a large fluffy multi colored ball under the dresser when we moved it.
