Many people keep rodents as pets, but some have better pet potential than others. Some require more space, care, or even specialized grooming than others. Explore this pet rodents list and decide if one of these fascinating creatures might be the right companion for you.
Gerbils Are Good Pet Rodents
Gerbils are popular pet rodents. There are several types of gerbils, although Mongolian gerbils are among the cutest and the ones most likely to be found in pet stores.
Domesticated gerbils look similar to hamsters, with a few exceptions. They have slightly broader heads, with very small ears, slimmer bodies, and a long tail. Their backs are arched, and they tend to move like mice. Their entire length, including their tails, runs about 8 inches long, on average.
Gerbils have short fur that comes in many colors, including basic colors like:
Gerbils as Pets
Gerbils make decent pets, but they're not ideal for young children. You may prefer just to watch them rather than hold them because they tend to nip, and they must be handled a lot as youngsters to overcome this trait.
Beyond that, these rodents are very active pets that take several naps throughout the day to recharge their energy. This means you'll see a lot more activity from them during the day than you would from a hamster, which is largely nocturnal. They love to burrow in their litter, and they'll climb anything that is in their habitat. They really need an exercise wheel, and they also love exploring the world from the safety of a hamster ball.
"Gerbils are territorial creatures, and I've never heard that there's really much difference in keeping two males together than two females, except that females may be slightly more inclined to fight occasionally, especially if they were introduced to each other after reaching maturity. What's really important is the introduction. The easiest thing would be to get two at the same time who have already been living together. That way, they already know each other, and you'll be introducing them both into neutral territory." -- Response to reader question from ashley

Guinea pigs make excellent pets that rarely, if ever, try to bite. They are very good-natured and social, and they seem to enjoy being cuddled as long as you hold them securely and don't attempt to turn them on their backs. They also learn to recognize their caregivers and will whistle at them in greeting when they approach.
"... go to a local pet store and pick up a guinea pig playpen and let them run around in it for safe exercise. Add a few cardboard boxes with doors cut out to play in." -- Reader comment from amanda
These are active creatures that like to have a lot of space and require roomy, well-ventilated habitats. They have an endearing habit of "pop-corning," which is a joyful little hop and kick combination.

According to the Rat & Mouse Club of America, domesticated mice are very cautious around humans, and it can take as long as three weeks of close, regular contact to gain their trust. Once they trust you, they'll readily step onto your hand without nipping.
Mice, like hamsters, are nocturnal, so you'll see the most activity from them at night. They are very active and love to have places to climb and safe items to chew.

"We had gerbils, hamsters, guinea pigs, and rats when my kids were growing up. I have to say that the rats, who entered the house as snake food but were rescued by my daughter, were the most successful in terms of interacting with my children." -- Reader comment from janmaus
Domesticated rats can make wonderful pets if they receive a lot of socialization. According to the American Fancy Rat and Mouse Associations, these rodents are extremely intelligent, curious, and active. They can learn to perform different behaviors if you take the time to train them. Males and females can make equally good pets, although the males do become a bit more laid back when mature.
Although rats are basically nocturnal by nature, but they can adjust to spend more time with you when you're available to play with them. Just make sure they have toys that satisfy their urges to exercise and chew, so they can keep themselves occupied when you can be with them.
Miscellaneous Rat Facts

With their soft fur, bushy tails, and adorable ears, chinchillas are cute and fun pets on the rodent family list.
General Chinchilla Appearance
Chinchillas are very attractive rodents that have lush coats and furry tails. Their eyes are large and round, and their large, erect ears operate as their cooling system. They are similar in size to a Guinea pig, and typically reach about 10 inches in length, with about an additional 5 inches worth of tail. They are mainly colored grey or beige with a darker coat on top and a lighter shade beneath.
Domesticated chinchillas can make good pets for adults and older children who understand these animals need to be handled gently. Chins are easily stressed if there is too much noise and activity around their living space. Most chins find it difficult to tolerate loud noises, so the noise level should be kept to a minimum as much as possible. This doesn't mean you have to keep your home as silent as a library, but do use common sense and avoid yelling, blasting the TV or radio, etc.
According to the Chinchilla Club, chins are crepuscular, and they tend to be most active around dawn, and then again around dusk. They do need daily time out of their cage, but keep a close eye on them because they love to chew.
Taming a Chinchilla
Taming a chinchilla is a matter of gaining the animal's trust, and this takes a good deal of time and patience. Tame chins can be fairly affectionate and will readily come to you when you open the cage door. However, they do like to nibble things in order to check them out, and this can include your fingers. Tamed chins learn to nibble gently, so frequent handling is necessary for them to get used to their caregivers.
Miscellaneous Chinchilla Facts
- Female chinchillas are dominant over males.
- Chins need social interaction and prefer to live with another member of their species.
- This rodent's lifespan averages about 10 years, but some chins live more than 20 years when given exceptional care.
- Chinchillas need to take special baths in "dust," or volcanic ash, to keep their fur and skin healthy.
"What about a degu? They make awesome pets... I just adopted a adult pair that were skittish (run at the sight of me) and only a week (later) they're letting my rub their chin, pet their whole body and everything and never been bitten." -- Reader comment from acorablackknight
Make Sure Your Pet Rodents Are Legal
Not all pet rodents are equally welcome across the United States. California and Hawaii, in particular, exclude some pet rodents in order to protect their natural wild animal populations and environments. A good rule of thumb to follow is that if you can buy a particular rodent at a major local pet store, it is probably legal to keep the animal where you live. However, it's always safest to check with your local Department of Natural Resources to make sure you aren't going to break any laws. Doing this before you purchase or adopt a rodent can save you the heartache of having to give the animal up later on.
