Here is the answer to what yesterday's mystery object was.
It is a guinea pig/chinchilla feeder! I never would have figured it out! Quite a few of you suggested a soap holder for the shower. I love this suggestion, and now wish I would have kept it and tried it as a soap holder! You guys are brilliant. Speaking of guinea pigs, I took these shots when we were in the pet store. I think he is so adorable!!
