since ferrets are reletivly new to the vets there is not many vacines for ferrets let alone the distemper one they tend to base them on cats, and have forgot the amount of times i have had to sign to say i am allowing the vet to use somthing on the ferret that is not registered for them.
asking friend on on=ther forum there is no vaccine for distemper for ferrets like i thought.
as far as i know canine vaccines are used in ferrets not cat vaccines .. the only licenced drug to use in ferrets is the jill jab (Delvosteron) as far as i am aware
