But aren't rats supposed to smell bad? I have never come across a rat that didn't stink. I would never have one as a pet because of this reason. Well, I don't like them either, but the smell is something I can't stand. I hate odors! I can't stand going near the rats at the pet store, and they are in tanks in our local pet stores...........clean ones too. I wish you luck in finding a solution. Maybe ask someone who works at pet stores. They might know of some product.
