  • Azithromycin is given by mouth or injection and is used on and off-label to treat a variety of infections. Give as directed. Common side effects include stomach upset. Do not use in pets that are sensitive to macrolide antibiotics. If a negative reaction occurs, please call your veterinary office.

  • Cheyletiellosis in rabbits is a condition caused by the common rabbit mite, Cheyletiella parasitovorax. This mite’s effects are sometimes called "walking dandruff" because they are large, whitish mites that crawl across the skin and hair of a rabbit and cause excessive flaky skin. Other clinical signs of cheyletiellosis include itching, scratching, and hair/fur loss. This species of mites can live in the environment for a short time and affect people and other animals, so it is important to follow your veterinarian's recommendations for treating the environment and all pets in the household.

  • Coccidial organisms, including Eimeria, are parasites that can infect rabbits, especially young and recently weaned rabbits. These organisms invade the intestinal tract of young rabbits and can progress to cause a fatal infection of the liver in many cases. Many rabbits show no signs, but if they do, they may have infrequent or intermittent watery, mucousy, or blood-tinged diarrhea. If your rabbit's diarrhea progresses to moderate to severe in intensity, your veterinarian will hospitalize your rabbit to provide supportive care until it is well enough to go home.

  • Common conditions of pet ferrets include diarrhea, intestinal foreign bodies, parasites, heart disease, and various tumors. This handout outlines the causes, clinical signs, and treatment options for each of these conditions. Any variation from normal should be a cause for concern and should be immediately evaluated by your veterinarian.

  • Common conditions of pet rabbits include upper respiratory tract infections, internal and external parasites, dental disease, E. cuniculi infection, gastrointestinal stasis, uterine problems, and pododermatitis (sore hocks). This article discusses causes, signs, and treatments for these conditions. Regular yearly check-ups enable an early diagnosis and treatment of some rabbit diseases. Whenever a rabbit stops eating, for whatever reason, it is important to take them to see your veterinarian immediately for an evaluation.

  • Encephalitozoonsis is a parasitic infection that can affect the kidneys, eyes, and nervous systems of rabbits. Many infected rabbits do not develop clinical signs until they are older or if they become stressed or immunocompromised. Common signs that may develop include heavy white plaques/growths inside one or both eyes, head tilt, eye twitching, and tremors or seizures. Treatments are available, though not all rabbits respond.

  • Ferrets are commonly affected by ear mite infestations. Many ferrets show no symptoms of infestation but you may notice your ferret shaking her head or scratching herself. Treatment for ear mites must be done under the guidance of a veterinarian familiar with ferrets.

  • Flea infestation is a common problem in pet ferrets, especially in ferrets that go outdoors or live in a house with dogs, cats, or other animals who have fleas. Affected ferrets may or may not be itchy, depending on their sensitivity to flea bites. Signs and treatment of fleas are discussed.

  • Fleas in hedgehogs are less commonly seen in comparison to cats and dogs but a similar treatment protocol under the direction of your veterinarian is required in order to control an infestation. This handout describes the clinical signs of fleas in hedgehogs and what to do (and what not to do) if your hedgehog is affected.

  • Rabbits can become infested with fleas, especially if they go outside or live in a house with other pets that have fleas. Rabbits with fleas may show no signs or may bite, lick, or scratch themselves. Young rabbits with heavy infestations may become anemic. There are no rabbit-specific drugs for managing fleas. Certain topical anti-parasite medications appear to be safe but should only be used under the guidance of a veterinarian familiar with rabbits.
