When I got the baby boys out this morning, they smelled really bad. The cage doesn't smell, just the rats themselves. It's probably super noticeable because they cuddle under my chin, so they are in close proximity to my nose. I gave them a soapless bath, and it really helped. Is there any soap that is safer to use on rats than others? I know that Dawn is used on animals in oil spills, and therefore seems to be safe, but I didn't want to use it before asking on here.
