Parasitic skin diseases
Lice and mites are the most common external parasites of ferrets. Lice are tiny, wingless, flattened insects that live within the hair coat; both the adults and their eggs are found attached to individual hairs. A mite similar to the scabies mite of people causes serious infestations in pet ferrets. Ear mites are very common in ferrets and can be transmitted between ferrets, cats and dogs.
