I had a ferret with a persistent ferret cough/bark. I took him to multiple vets and he was on multiple meds. I was a mess listening to him at night and feeling utterly helpless. Finally, I found a vet who put him on a nebulizer with no meds. I put the ferret in a carrier and wrapped a plastic bag around the small carrier. I put the ferret in the carrier,and left only a small opening for the nebulizer to release mist. I had to do that every night for a few months. I did it while watching TV and talking to my little fellow for about 30 minutes a night. Then the problem just disappeared except for an occasional harsh cough maybe twice a year. The ferret was checked out for heart disease and also put on a multitude of antibiotics first. There was no heart disease. I cannot tell you how helpless I felt. Nothing worked until the nebulizer. You can get one online. Just close up the garbage bag over the small carrier with one of those black heavy garbage bags that closes off, leaving a small opening. [Posted in FML 5652]
