Hi, my name is Kim and I'm a vet tech in Minnesota. We have 4 fuzzies and have had all 4 of them vaccinated with Imrab 3. This is licensed and approved for all ferrets by the USDA. Local laws in the Twin Cities metro area require rabies vaccs. I find it highly suspicious that your current veterinarian is not aware of this vaccine. At my clinic, we have vaccinated several other ferrets and have never had any problems. I would recommend that you get a second opinion, possibly someone who is a little more up-to-date on their studies of ferret medicine. Kim Kaufman, CVT [Posted in FML issue 1882]
