what exactly causes horrible breath? My stray cat Willoughby (or as we have been calling him, Apathy) has absolutely foul smelling breath. His teeth look almost perfectly clean. I am guessing him to be about a year old. His gums look normal, part pink and part gray. They gray part looks natural, not like it is discoloured. ButI could be wrong. What is making his breath smell so disgusting?
