Dear Sue: >I will try to keep it short. I have a male ferret, been boucing but now >a litle depressed acting does ear-mites do that. I've been treating it >with ear drops. I'll keep it short too. Ear mites can cause lethargy, but usually don't - even severe infections rarely cause significant lethargy - they more often cause scratching at the ears. Four questions - 1) Have you seen a vet? 2) What drops are you using? 3) Where did you get them? 4) Does you ferret have a lot of black junk in his ears?
