Sounds like the ferret's ear is painful. Could you have caused some trauma to the tympanic membrane by deep cleaning? Sensitivity to the ear cleaner or infectious causes are possibilities too. This might be one to get checked out. P.S. Currently the most efficaceous treatment against ear mites is Revolution (selamectin). I use the puppy/kitten dose. This not only takes care of ear mites but is also effective against fleas, ticks, hookworms, roundworms, and is a heartworm preventative. Marc Kramer, DVM -- Marc H.
