To the person who posted about bad breath in a ferret: Since you've already determined that there's nothing wrong with the teeth, you need to check for kidney disease. This requires a blood test to check for BUN and creatinine levels. Kidney disease is a silent killer, and bad breath is one of the few ways to catch it early (along with regular blood tests). I'm not saying that's what your ferret has; I'm just saying I think you should have it checked. Linda [Posted in FML issue 1572]
