Small Mammals + Preventive Care & Wellness

  • Any cage used to house a pet rodent must be easy to clean, as poor husbandry and hygiene can contribute to illness in these animals. The bigger the cage, the better, as rodents need room to exercise and explore. While some species of rodents may be housed in pairs or groups, intact (unneutered) males and females should not be housed together, or they will breed. Different species should not be housed together. Rodents should be provided with paper bedding or shredded or recycled paper in their cages. Cleaning, enrichment, and exercise recommendations are also discussed.

  • A large, well-ventilated cage with a plastic bottom and wire walls and top is suitable. Wire-bottom rabbit cages are acceptable, but to decrease foot trauma, at least half of the wire floor should be covered with plastic, Plexiglas, or untreated wood. The bottom of the cage can be lined with hay or commercially available recycled paper products. Rabbits can be trained to use a litter box. Rabbits should never be allowed to run loose in the house unless they are supervised or contained in a rabbit-proof room.

  • 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.

  • All pets, including rodents, sugar gliders, and hedgehogs, need an initial examination by a veterinarian and at least an annual check-up to allow for early detection and treatment of potentially life-threatening diseases. During this visit, your veterinarian will perform a physical examination and various diagnostic tests to determine your pet's state of health and to see if your pet might be harboring any diseases that require treatment.

  • Gerbils generally make good family pets but should never be left unsupervised with small children. If well-socialized from a young age and treated gently, they can be wonderful pets. The incisors (front teeth) of all rodents grow continuously throughout the animal's life. Gerbils do not require vaccines, but they should have annual examinations.

  • If well socialized from a young age and treated gently, hamsters are generally slow moving, reasonably easy to handle, and affectionate. Hamsters make good family pets but should never be left unsupervised with small children. Hamsters should have annual physical examinations and fecal tests for intestinal parasites.

  • 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.

  • 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.

  • A pet sitter can give your pet the care they need if you have a busy schedule or are traveling. Pet sitters take care of your pet in your home or theirs, and can do much more. Be sure to interview any potential sitters and use trusted friends, your vet, or online resources when looking for sitters.
