Gerbil

— A Desert Digger That's Active Day and Night.

The pet gerbil kept in homes today is almost always the Mongolian Gerbil, a small desert rodent native to the arid grasslands of Mongolia and northern China. Unlike the strictly nocturnal hamster, gerbils are diurnal — active during the day as well as at night — and their natural burrowing instinct, docile temperament, and low tendency to bite have made them a longstanding favorite among small-pet owners, particularly in households wanting a pet awake at more convenient hours than a hamster.

The Gerbil has short, dense fur in agouti (wild-type) most common, plus black, white, and other bred variations, with a light pattern year-round.

Gerbil

Personality

CuriousGerbils are naturally inquisitive, actively exploring and digging through their habitat rather than staying hidden for most of the day.

DocileRarely bites, even under startled circumstances, making the species comparatively easy to handle with gentle, consistent interaction.

SocialA genuinely social species that does best in same-sex pairs from the same litter — solitary gerbils can become withdrawn or depressed.

ActiveDiurnal activity patterns mean gerbils are genuinely interesting to observe and interact with during normal daytime hours, unlike most small rodent pets.

Care & Needs

HousingA solid-bottomed enclosure with deep substrate (several inches at minimum) supports the breed's strong natural digging instinct; wire-floored cages can injure their feet.

CompanionshipKeep same-sex littermates together from a young age; introducing unfamiliar adult gerbils later carries real risk of serious fighting.

EnvironmentA dry, low-humidity environment kept between roughly 65-75°F suits this desert-adapted species best, away from direct sunlight and damp conditions.

DietA commercial gerbil-specific seed and pellet mix as the base, with fresh vegetables offered in moderation and clean water always available.

Did You Know?

Nearly all pet and laboratory gerbils in the United States descend from a single 1954 research shipment of about 20 pairs, similar to the single-founder-population story behind the Syrian hamster.

Health & Common Issues

Respiratory InfectionsSneezing or labored breathing can indicate a respiratory infection, which warrants a prompt exotic-vet visit given how quickly small-rodent illnesses can progress.

Nasal Dermatitis (Porphyrin Staining)Stress or overcrowding can cause gerbils to over-produce a reddish secretion around the nose and eyes, sometimes accompanied by skin irritation and hair loss.

Obstructive Ear DiseaseA documented condition in the species affecting the ear canal; unusual head tilting or balance issues are worth having evaluated by a vet familiar with small mammals.

Training & Exercise

Handle gently and consistently from a young age to build trust, since gerbils are generally receptive to calm, regular interaction.
Provide ample digging substrate as a built-in outlet for the species' strong natural burrowing instinct.
Introduce potential same-sex cage mates only as young littermates, or through a slow, carefully monitored process if pairing unfamiliar adults.
Offer chew toys and enrichment items, since gerbils' teeth grow continuously and need regular wear.

History & Origin

Native Range The Mongolian Gerbil is native to the arid steppes and desert grasslands of Mongolia and northern China, where wild populations remain widespread.

1930s Gerbils were first imported to the West for scientific research, valued for their hardiness and manageable size in laboratory settings.

1954 A research shipment of gerbils to the United States became the foundation population for both later research colonies and the pet trade.

Today A well-established small pet, valued particularly for its daytime activity pattern and comparatively docile, easy-to-handle temperament.

Frequently Asked Questions

Are gerbils better pets than hamsters?

It depends on what an owner wants — gerbils are active during the day, generally more social (and should be kept in pairs), and tend to bite less, while hamsters are solitary and mostly active at night. Neither is objectively better; the right choice depends on when an owner wants to interact with the pet and whether housing two animals together is workable.

Can gerbils live alone?

It's not recommended — gerbils are a social species, and keeping a same-sex pair (ideally littermates introduced young) leads to a noticeably happier, less stressed pet than solitary housing, which is better reserved for situations where pairing isn't medically possible.

Do gerbils bite?

Rarely — gerbils are known for a notably docile temperament and low bite tendency compared to many small rodents, especially with regular, gentle handling from a young age.
