Not too long ago, Dr. Williams recommended isopropyl alcohol instead of mineral oil for cleaning ferret ears. I use it now, and they still don't like ear cleaning, but it works great. I dip a cotton swab in the alcohol and then wipe around the ear where I can see reddish-brown wax buildup, and it comes right off. I stay away from the ear canal because that's the part that's most sensitive and I don't want to rupture their eardrums. Linda [Posted in FML issue 1321]
