Took in two ferrets 3 months ago. Vet exam confirmed one with suspected insulinoma, and a surprise of ear mites. Started on pred, treated this ferret and his buddy with Revolution. All was well until this past Wednesday morning. Found the ferret in what I thought was a insulinoma seizure. I soon realized this was different. He seemed *aware*, just unable to maintain any kind of balance. Threw his head from side to side, barrel rolled, eyes *jittery*. Off to the vet. BG was 110. Right ear gunk, she couldn't see down deep. Ferret sedated, ears flushed. What came out of his right ear was a hardened wax/mite debris plug. Under the plug was infection, and a ruptured eardrum. Little guy is fine now, on antibiotics and ear meds. Ear mites, fleas etc have not been much of a problem here till the last couple of years. Mild winters, sudden hot spring/summers. Bugs like that. I am now back to ear checks/cleanings more often. And a really good flush/cleaning with vet prescribed meds after any mite treatment. The one I have now is safe even for ruptured ear drum, not all are. Someone recently posted about a ferret with a Cuterebra in it's chest. My vet says she normally sees 2 or 3 dogs a year with these, this year she has seen over 20. I don't want to see even one. Ardith Reno, Nevada [Posted in FML 7557]
