I've become quite the expert at baths (I only say this because others have!

). I don't recommended anyone who's not extremely experienced in wriggly rats try my method, tough. I've gotten down to 2 minute baths at the sink. But I do end up very scratched up, heh.

My advice is always to have everything ready before bringing the rat in.
Anyhow, remember that rats do bathe themselves and for the most part, they don't need a lot of baths. Too much bathing disrupts the natural oils in their skin/fur that keeps it healthy. That said, the occasional bath is fine, but do prepare to end up scratched! Some wear a long sleeved shirt to minimize. Though, if you're lucky, you end up with rats that love baths. Rare, but there are some!
Oh! I just noticed you're in Louisville. Hello, neighbor!
