Fat-tailed gerbil
Pachyuromys duprasi · also called Duprasi, Duprasi gerbil, Fat-tailed jird, Beer-mat gerbil
A docile, hamster-like desert gerbil with a distinctive club-shaped fat-storing tail; calm and rarely bites, insectivorous in the wild, and usually best kept singly due to same-sex aggression.

Part of the Gerbils
Burrowing desert and steppe rodents of the subfamily Gerbillinae kept as active, dry-climate small pets. They are adapted to arid conditions, love to dig and sand-bathe, and range from the social Mongolian gerbil to the docile, insectivorous fat-tailed duprasi.
Habitat & space requirements
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.
Color & pattern variants
Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.
Habitat & enclosure
Duprasi need a large, secure glass tank or bar-free enclosure (a long aquarium-style tank works well) with a tight-fitting mesh lid, since a solid-sided enclosure prevents chewing out and allows deep, safe substrate. Provide a thick layer (15-30 cm+) of dig-friendly substrate such as a paper/aspen mix, with a sand bath area (children's play sand or chinchilla sand, not dust) that they use to keep their fur clean and degreased. Add hides, tunnels, chews, and a solid-surface wheel.
As Northern Sahara desert animals, they need warm, dry conditions; keep them at roughly 20-25 C, well away from damp and cold drafts, with low humidity. They burrow in the wild and appreciate deep substrate for tunneling. No UVB or water features are required, but a dry, warm, escape-proof, sand-equipped setup is key to their welfare.
Substrate
Provide deep (15 cm or more) sandy substrate, ideally a mix of children's play sand and paper-based or aspen bedding so they can dig stable burrows. A separate shallow dish of chinchilla sand for sand-bathing keeps their coat clean and oil-free. Avoid dusty or cedar/pine shavings, which irritate their respiratory system.
Equipment & setup
House them in a large glass tank or deep-base bin cage (60 x 30 cm minimum) with a secure mesh top, kept around 20-24 C with no heat lamp normally needed indoors. Add a solid-surface 20 cm+ running wheel (no rungs), ceramic hide, and gnaw items; they tolerate handling better than Mongolian gerbils. Keep humidity low and ventilation good, as they are a desert species prone to respiratory issues in damp conditions.
Diet
Unlike herbivorous gerbils, duprasi are largely insectivorous in the wild, so live or dried insects (mealworms, crickets, and similar) should be a regular and important part of the diet rather than an occasional treat, alongside a good gerbil/hamster grain mix and small amounts of safe vegetables.
Offer insects several times a week to meet their protein needs, scatter dry food to encourage foraging, and provide constant fresh water. Keep sugary foods to a minimum and supply chews and safe wood to wear down the continuously growing incisors.
Behavior & temperament
Duprasi are famously placid and are often compared to Syrian hamsters in handling temperament: docile, slow-moving for a gerbil, and rarely prone to biting, which makes them appealing to keepers who want a calm small mammal. They are largely nocturnal/crepuscular and enjoy digging, sand-bathing, and foraging.
Toward their own species they can be aggressive and even cannibalistic, so although some keepers attempt carefully introduced young same-sex pairs, solo housing is the safest default and fighting requires immediate separation. Enrich with deep digging substrate, a sand bath, tunnels, foraging for insects, and a wheel; handle gently and support the body, and never grab the tail.
Health
Common problems include obesity (a healthy tail is plump but the body should not be overweight; over-rich diets cause issues), respiratory and skin problems from damp or dirty conditions, overgrown teeth, and fight wounds when cohoused. A sudden thin or shrunken tail can indicate illness, stress, or poor nutrition and warrants attention.
Keep the enclosure dry, warm, and clean, provide a sand bath to prevent greasy coat and skin issues, and monitor weight and the condition of the tail. Use an exotics-experienced vet for lethargy, weight loss, breathing trouble, or wounds; as desert prey animals they mask illness, so subtle changes matter.
Tips, DIY & hacks
Offer occasional live or dried insects (mealworms, crickets) since duprasis are more insectivorous than other gerbils and need the extra protein. Watch the tail thickness as a health gauge: a plump tail means good condition, a thin tail signals weight loss or illness. They are best kept singly or in carefully introduced same-sex pairs, as adults can become territorial.
