Strictly speaking, rodent is a neutral term for any member of the order Rodentia. Let's not kid ourselves though, there is a distinct negative connotation. Rodents may simply be mammals whose teeth grow for life but the term brings to mind rats, mice and other vermin. Historically rodents are unpopular for two reasons, peskiness and pestilence.Until recently I thought of rats as the big rodents and mice as the small ones. Wrong. Apparently beavers are the King of Rodents.
