What do rats hate to smell?

Mice smell much more than rats. They smell if you don't clean their cage every few days! The animals themselves don't usually smell as they clean themselves. Also, you shouldn't do this to mice, but you can give rats bathes, but you can only give them one about once every month. Pet Stores also sell spray that you can apply to mice and/or rats that will help the smell.The oil in their fur will come off if you do.
