Yes, they smell.

Do they smell alot?

Only if you don't clean up after them for a while.

Do they smell bad?

Not in my opinion.

What does smell?

Dead Rats (They start stinking IMMEDIATELY, it seems like), any rodent ANYTHING.. Especially after feeding, when they run around and piss and crap all over the CLEAN tub you had a few minutes before..
