A couple days ago I removed a box from Blaze's cage because the pee on the top seemed to sparkle almost like tiny mini crystals. Since the box was old I thought it was just like a gross mold or something growing on it so I got rid of it. I just cleaned their cages yesterday and replaced the box and this morning it has the same crystal thing going. Is there something wrong with him? I can't really get a picture I have no decent camera that would capture it.
