Like cats, rats clean themselves. In fact, if a rat looks dirty or scruffy, he's probably sick. That's not normal. Dogs look dirty all the time because they do not clean themselves. But rats do. They spend a lot of time cleaning themselves. In fact, if you're holding a rat and he starts cleaning himself, that's a sign that he feels at ease with you, because it's a vulnerable time for them.
