This is for Tracy's question about ear mites.... I had to treat all of mine recently for this and having done the ear medication thing with a bunch of cats before, I was not looking forward to daily treatments on a group of wiggly ferts. So instead of using Tresaderm, we treated all of them with Ivomec (given orally). We treated all of them at the same time, and repeated the process about 14 days later. So far, looks like we got rid of them. Ivomec is not "approved" for use in ferrets (but what is???). I was told however that it was tested on ferrets, so it is safe to use....just never officially labeled for it. Since it is a heartworm preventative as well, it might be recommended that the ferrets remain at the vets for a while after the treatment, just as a precaution in case of a possible reaction. I already had mine on a preventative and knew that they were not sensitive to it and they did not have heartworms so that may have had something to do with my vet allowing me to use this treatment......not really sure, but it is SO much easier than the standard treatment it is worth checking with your vet about it. If your vet doesn't recommend using it, then I would ask him/her about treating the other ferrets with the Tresaderm as well, as a preventative step. Usually, if they don't have mites already, a couple of times a week is sufficient until the mites are gone in the affected pet. If not, there is always a possibility that the mites will just keep moving from pet to pet. We also recommend treating the entire pet (paws especially) with a safe flea powder or spray because mites can live on other areas of the pet which makes it more difficult to get rid of them. Hope this helps you! Stacia and the fuzzies [Posted in FML issue 2435]
