I <3 this thread.
Unlike most of you, I don't have a dog or a cat. I HAVE TWO CHINCHILLAS!
They are really fury squirmy animals and when I get them out for free time sometimes they get away from me. As soon at I'm out of sight, Bronco goes into the kithchen and squeezes himself under the dishwasher. I've grown so tired of taking it apart to get him out. Bronco also has a favorite spot in the bathroom (aka: Chin play room). Under my sink, apparently there is a gap that they can jump into which leads to the space under the cabinet. Basically, one second Bronco is there beside me on the floor and in a split second he's gone. As soon as I figured it out, I just covered the hole with wrapping paper.
I used to leave my rug in the bathroom during playtime until I figured out what they were doing. The little buggers used it as their toilet. They would go to the far corner of the rug, stick out their little butts and pee. Now I just take the rug out with everything else.
And, Thunder, oh Thunder. He is more adventurous of the two. He has a routine. He jumps onto the toilet seat. Then, he uses his front paws to unroll some toilet paper. AND THEN! He jumps onto my counter top and runs around until everything is on the floor.
I love them. They actually had to go to the vet today. It looks like they are allergic to the new dust I was using...poor boys.
