Small Mammals + Parasites

  • 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.

  • Fluralaner is given by mouth or applied topically and is used to treat flea and tick infestations, and also off-label to treat certain types of mange and mites. Give as directed. Side effects are uncommon but may include stomach upset or neurologic symptoms. Do not use in pets with a history of seizures. If a negative reaction occurs, please call the veterinary office.

  • Guinea pigs can be hardy and easy to care for when provided an appropriate environment for their unique needs. Like all animals, guinea pigs are susceptible to certain problems and diseases. This handout outlines the diagnosis, treatment, and prognosis for some of the more common health problems of guinea pigs.

  • Common conditions of pet hedgehogs include internal and external parasites, ringworm, cancer, pneumonia, gastrointestinal disease, and obesity. Signs of illness or disease are often vague and non-specific, such as lack of appetite and lethargy. Therefore, any deviation from your hedgehog’s normal habits should be cause for concern and should be evaluated by your veterinarian.

  • Hedgehogs can have several unique problems, including cancer, dental disease, obesity, and foreign bodies. It is important for an owner to understand what these problems are so veterinary care can be provided to their hedgehog when needed and in a timely manner.

  • Metronidazole is given by mouth or injection and is used off-label to treat certain anaerobic bacterial and protozoal infections and gastrointestinal conditions in dogs, cats, and other animals. Give as directed. Side effects may include nausea, vomiting, diarrhea, regurgitation, decreased appetite, tiredness, and drooling. Do not use in pets that are allergic to it, are debilitated, or are pregnant or nursing. If a negative reaction occurs, contact your veterinarian.

  • Mites and lice can cause trouble for guinea pigs. Some mites may cause no clinical signs, while others can cause extreme signs, including itchiness, crusty skin, hair loss, and secondary bacterial skin infection. This article summarizes diagnosis and treatment.

  • Mites affecting pet hedgehogs, often called quill mites, are fairly common. Initially, an affected hedgehog may become itchy but if mites are left untreated, the clinical signs can become severe. Treatment for your hedgehog should always be under the guidance of a veterinarian.

  • Moxidectin is an avermectin antiparasitic that is used to prevent heartworms and treat intestinal parasites. Imidacloprid treats and prevents fleas. These two drugs are combined in one topical product for use in cats, dogs, and ferrets. Use as directed. Side effects are uncommon and usually short-lived, however, if you suspect an overdose or an adverse reaction to the medication, call your veterinary office immediately.

  • The common rabbit pinworm, Passalurus ambiguus, is an intestinal parasite. It does not posea serious health threat to rabbits, but it can cause uncomfortable itching and skin inflammation or redness around the anus. Rabbits become infected with pinworms by eating feces that contain pinworm eggs. Pinworms are challenging to treat because rabbits are coprophagic, so can potentially reinfect themselves during treatment.
