All pet rodents must be fed a good, high quality rodent chow available at pet stores. Many veterinarians also recommend offering hay and fresh vegetables to rodents to encourage chewing and the wearing down of their continuously growing teeth. Diets containing seeds and nuts are not recommended, as they are high in fat and low in nutrition. Water may be offered in a bowl or in a sipper bottle. Seeds, nuts, pasta, unsalted popcorn, or a whole grain cracker can be offered as occasional treats. You can also feed your rodent fresh, well-cleaned vegetables daily and occasionally give a small amount of fruit. Unlike most pets, guinea pigs do not make their own vitamin C and should be fed a commercial high fiber guinea pig pellet with added vitamin C. Chew toys made from hard wood are commercially available in pet stores for rodents and should be offered to help prevent overgrowth of the incisors.
Rabbits are herbivores and are considered grazers. Rabbits should have a daily diet of mostly hay, a smaller amount of fresh vegetables, and a limited number of pellets. Hay is the most important part of a rabbit's daily intake. A common cause of obesity and soft stool is over-feeding pellets. Rabbits should be fed and provided with fresh water daily; hay should be available at all times. A pet rabbit’s diet should be supplemented with a variety of leafy green vegetables every day. The high sugar content in fruits (and even carrots) may upset the normal GI tract bacteria if given in excess. Rabbits engage in coprophagy, which means they eat their own feces at night. These fecal pellets are called cecotropes and serve as a rich source of nutrients, specifically protein and vitamins B and K.
Ferrets commonly get infestations of an ear mite called Otodectes cynotis. Many ferrets show no symptoms of infestation. Subsequent problems of the ears are rare. Ear mites are acquired from other affected animals at the breeders, in pet stores or animal shelters.
Due to their well-deserved reputation as escape artists, ferrets should be housed in a cage that can be securely closed and/or locked. The cage should be as large as you can afford; a suggested minimum size might be 24 x 24 x 18 high (60 x 60 x 45 cm).
Ferrets have several unique problems; understanding these problems will allow you to better care for your pet and minimize future health care problems.
Mast cell tumors are the most common skin tumor found in ferrets. They can also be found internally on the spleen. They arise from a cell type called a mast cell. In dogs and less so in cats, these tumors can vary from benign to highly malignant.
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 the sensitivity of the individual animal to flea bites. Early in the infestation, there may be no signs that your ferret even has fleas. Young ferrets with heavy infestations may even become anemic as the fleas feed over time. Some topical medications used to treat fleas in dogs and cats appear to be safe in ferrets but should only be used under the guidance of a veterinarian familiar with ferrets.
Hedgehogs can acquire external parasites. Flea infestation is not a common problem in pet hedgehogs. Fleas are a small insect parasite that may take up residence on your hedgehog, especially if exposed to fleas outdoors or in a house with dogs, cats or other animals who themselves have fleas.
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 cat medications appear to be safe but should only be used under the guidance of a veterinarian familiar with rabbits. It is very important to treat the environment, as well as the pet.
Fluconazole is an antifungal medication used off label in cats, dogs, and small mammals to treat fungal infections, especially those in the brain and spinal cord. It is given by mouth in the form of a tablet or liquid suspension, and is also available as an injection for hospital use. Common side effects include gastrointestinal upset such as decreased appetite, vomiting, and diarrhea but liver toxicity can also occur. It should be used with caution in pets with liver or kidney disease, or pregnant or lactating pets. If a negative reaction occurs, call your veterinary office.
