Ear mites are tiny parasites that are related to ticks and target the ear canal of animals, says Robin Urie, DVM, owner and veterinarian of Warm & Fuzzy Veterinary Center in Middle River, Maryland. The highly contagious parasite known as Otodectes cynotis is the culprit that causes ear mites in ferrets, as well as dogs, cats, and other animals. Ear mites are extremely common, and in rare cases, can even infect people, Dr. Urie says. The most common ways ferrets get ear mites include: They were adopted with an existing infestation. They were exposed to a new animal with an infestation, such as another ferret, dog, cat, or even wildlife if they’re allowed outside. They were exposed to contaminated bedding containing mite eggs. The pet parent unintentionally brought mite eggs or mites home on their clothing. This could happen if a person was in contact with another animal who has ear mites. Many times, pet parents won’t realize when a ferret is infected with ear mites, and these parasites can easily spread to dogs and cats as well, says Walter Merker, DVM, exotic animal veterinarian at Orange Grove Animal Hospital in Tucson, Arizona. Signs of ferret ear mites include: Redness to the pinna (outer ear) Redness to the ear canal Excessive dark (brown or black) waxy discharge from the ear canal Thick, milky discharge from the ear canal Itching of the head and ears Bleeding or scabbing in and around the ear Hair loss along the sides of the face and ears In severe cases, a head tilt, changes in pupil size, and facial drooping can occur, Dr. Urie adds. If you notice that your ferret’s ears are red and/or that they’ve been itching excessively, she recommends scheduling a vet appointment. The following symptoms warrant an urgent vet appointment: Any unusually colored or smelling discharge from the ear canal Bleeding or scabbing in and around the ear Hair loss around the face and ears Head tilt Changes in pupil size Facial drooping Without treatment, ear mites can lead to inflammation and secondary infection.,Jump to section Ear Mites in Ferrets Ear Infections in Ferrets Other Reasons for Red Ears in Ferrets Preventive Care: Keeping Ferret Ears Healthy
