Small Mammals

  • Rats are extremely intelligent, inquisitive, interactive, and social. If well socialized from a young age and treated gently, they are easy to handle, affectionate, and rarely bite unless provoked. Rats generally make good family pets but should never be left unsupervised with small children. Rats live about 2 to 3 years. The incisors (front teeth) of all rodents grow continuously throughout the pet's life. Rats should be examined by a veterinarian at least once a year and twice a year as they get older.

  • Prairie dogs (most often black-tailed prairie dogs) are becoming popular as pets. Like all rodents, they have teeth that continually grow throughout life. They are active, playful and sturdy rodents and can make wonderful, affectionate pets if purchased young, socialized properly and given lots of attention.

  • Pet rodents, sometimes also referred to as pocket pets are very popular pets. Hamsters, rats, mice, gerbils, and guinea pigs are the most common rodents kept as pets. They make good first pets for young children and as a rule require minimal care.

  • Guinea pigs live, on average, 5-6 years; although some can live to 8-10 years of age. Their teeth grow continuously, throughout life, and it is critical that they eat grass hay, such as Timothy hay, every day to help them wear down their teeth as they grow. Young guinea pigs display a unique behavior called popcorning when they are happy, in which they jump straight up in the air and let out squeals of delight. Guinea pigs reach sexual maturity at around 3-4 months of age; therefore, if young males and females are housed together, they should be separated by this age, otherwise they are likely to breed. The average gestation period for guinea pigs is 63 days. If gestation continues over 70 days, the guinea pig should be seen immediately by a veterinarian, and it is likely that the entire litter will be stillborn.

  • Oxytetracycline/polymyxin B ophthalmic (brand name Terramycin®) is a combination antimicrobial medication used to treat certain types of bacteria (gram-positive and gram-negative). It is used to treat eye infections in cats and dogs. It is used “off label” or “extra-label” to treat eye infections in avian species, hedgehogs, and rabbits. Oxytetracycline/polymyxin B comes in ointment form.

  • Penetrating wounds can look minor on the surface but may cause severe injury below the skin. A thorough assessment requires sedation or anesthesia and surgery may be required to address the extent of the injury. This handout outlines first aid steps a pet owner can take while transporting their injured pet to the veterinary hospital.

  • It is not difficult to find your pet the extra care they may need if you have a busy schedule or are traveling. With the excellent pet sitter options available today, having a pet at home does not mean you cannot take a vacation every once in a while. Be sure to interview any potential sitters and use trusted friends, your vet, or online resources when looking for sitters. Hiring a pet sitter for your pet may be like a vacation for them as well!

  • Phenobarbital is given by mouth or as an injection to treat seizures or to sedate your pet. Common side effects include sleepiness, increased thirst, urination, and/or appetite. Do not use this medication in pets with liver, lung, or kidney disease or those that are allergic to barbiturates. If a negative reaction occurs, call your veterinary office.

  • 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.

  • Polysulfated glycosaminoglycan is an injectable disease-modifying osteoarthritis drug (DMOAD) used to treat non-infectious and traumatic arthritis in dogs. It is also used off-label in cats and small mammals. If administering this medication at home, follow your veterinarian’s instructions and dispose of the needle and syringe appropriately. Side effects are rare when given according to label recommendations and at prescribed intervals. Do not use this medication in pets with a known hypersensitivity to it, in pets with known or suspected bleeding disorders or immune-mediated arthritis, or in pets with severe kidney or liver disorders.
