Not all pets need lots of space to bring joy into your life. Small rodent pets may be compact, but their personalities are anything but small. Some species are affectionate and enjoy human interaction, while others are more independent observers. Many are naturally nocturnal, which may not suit every household schedule.
That said, when given proper housing, enrichment, and a balanced diet, these animals are generally easy to care for. If you’re hoping to welcome a small, furry friend into your home, here are 10 popular small rodent pets to consider.
Tip
Pet rodents are delicate creatures. Anyone handling them—especially children—should always use slow, gentle movements. 
1. Syrian Hamster
Also known as the golden or teddy bear hamster, the Syrian hamster usually lives around two to three years. These hamsters prefer to live alone and need their own enclosure. When socialized from a young age, they often grow into friendly pets. However, because they are nocturnal, they may become cranky if disturbed during daytime sleep.
Species Overview
Length: 5–7 inches
Weight: About 5 ounces
Appearance: Golden-brown fur with a lighter belly; many coat colors and lengths exist
2. Dwarf Hamster
Certain species of dwarf hamsters can happily live in same-sex pairs or small groups. Their lifespan can reach up to three years. While some have a reputation for being a bit nippy, most respond well to calm and gentle handling.
Species Overview
Length: Around 2 inches
Weight: About 1 ounce
Appearance: Gray-brown coat, often with a dark stripe along the back and a pale belly
3. Chinese Hamster
The Chinese hamster is not technically a dwarf hamster but remains very small. They are less common as pets and can be tricky to handle due to their speed and size. Their cage must have narrow bar spacing or be a secure glass tank to prevent escapes.
Species Overview
Length: 3–4 inches
Weight: Around 1 ounce
Appearance: Dark brown back, black stripe along the spine, ivory underside
4. Mongolian Gerbil
The energetic Mongolian gerbil thrives in a same-sex pair or small group. Getting them while young helps build trust. With frequent interaction, gerbils can become quite tame, though their high activity level can make them difficult to hold for long.
Species Overview
Length: About 4 inches
Weight: Around 2 ounces
Appearance: Mix of gray, gold, and black fur with a pale belly and long furry tail
5. Fancy Mouse
Domestic fancy mice are quick and sometimes shy, but consistent gentle handling can help them grow comfortable with people. Females often live well together, while males may fight if housed in the same enclosure.
Species Overview
Length: 5–7 inches including tail
Weight: 1–2 ounces
Appearance: Wide variety of coat colors and patterns; long tail
6. Common Rat
Pet brown rats are highly intelligent and very social. They usually do better with a same-sex companion rather than living alone. With regular interaction, rats can become affectionate and even learn simple tricks. Daily time outside the cage is important for their mental and physical well-being.
Species Overview
Length: 9–11 inches
Weight: 12–23 ounces
Appearance: Various coat colors; long hairless tail and noticeable whiskers
7. Guinea Pig
The gentle guinea pig often lives five to seven years and is known for being easy to handle. They rarely bite, even when nervous. As social animals, they usually do best with a companion. Their diet must include fresh hay, vegetables, and adequate vitamin C.
Species Overview
Length: 8–10 inches
Weight: 25–42 ounces
Appearance: Rounded body, no tail, large head; many color combinations
8. Chinchilla
The chinchilla resembles a rabbit and is active and playful, especially at night. They prefer exploring over being held, but with time and patience, they can still bond with their caregivers.
Species Overview
Length: 10–14 inches
Weight: 15–25 ounces
Appearance: Extremely dense, soft fur; bushy tail; colors include gray, white, black, and beige
9. African Dormouse
The tiny African dormouse looks a bit like a miniature squirrel and is fascinating to watch. Because they are skilled escape artists, they require a very secure enclosure with climbing structures and plenty of space.
Species Overview
Length: 3–4 inches
Weight: 1–2 ounces
Appearance: Large eyes, rounded ears, bushy tail; gray or brown tones
10. Common Degu
Native to Chile, the social degu naturally lives in groups in the wild. In captivity, they do best in pairs or small groups. When handled frequently from a young age, degus can become friendly and may even enjoy cuddling.

Weight: 6–11 ounces
