Fat-Tailed Gerbil — care sheet

Beginner–Intermediate. Exceptionally docile and rarely bites — but not a standard seed-fed gerbil. The duprasi is insectivore-leaning (it needs insects/protein), does best in a deep, dry, sandy, warm setup, and is often happiest kept alone. Detailed husbandry rests on a smaller pool of specialist sources, so a duprasi-savvy exotic vet is worth finding.

Unlike seed-eating gerbils, the duprasi is strongly insectivore-leaning — live or dried insects (mealworms, crickets) should be a regular, important part of the diet, aiming for a higher protein intake (around 18%). Offer these alongside a good-quality gerbil or hamster seed mix and small amounts of vegetables. Keep watery vegetables limited (a desert species — too much moisture causes diarrhoea). Fresh water always available.

A secure glass tank or large barred cage with a solid floor and a deep layer of sand (or a sand-and-soil mix) at least 15–20 cm deep, since they love to dig — in the wild they burrow up to a metre down. Add a separate sand bath, hides, tunnels, safe wood to gnaw and a solid wheel. Keep the setup dry, well ventilated, warm and out of direct sun.

Unusually for a gerbil, duprasi are more tolerant of solitude and often live perfectly happily alone. A carefully matched same-sex pair (ideally raised together) can work, but sudden fall-outs happen without warning — so for many keepers a single, well-handled duprasi is the safest choice. (This is the opposite of the strictly-social Mongolian gerbil.)

A desert animal that needs warm, dry conditions and copes badly with damp and humidity (which cause respiratory illness). Keep the room about 20–25°C with dry sand, good ventilation, and no direct sun or overheating.

Deep sand or a sand-and-soil mix, at least 15–20 cm deep and kept dry, so they can dig and burrow.

Plenty of deep sand to dig, a sand bath to roll in (essential to keep the coat from turning greasy), and foraging by scattering seeds and hiding insects to hunt. Add tunnels, hides, safe gnaw-wood and a solid wheel.

A regular clean sand bath keeps the coat from becoming oily. Like other rodents their incisors grow continuously, so provide constant safe wood or hard items to gnaw; watch for overgrown teeth (drooling, dropping food, difficulty eating).

None specifically documented — the protein need is met by insects, not a supplement. Don’t improvise a supplement regime; a duprasi-savvy vet can advise if one is needed.

A body of about 10 cm plus a short, club-shaped tail; pet duprasi typically weigh about 40–60 g (wild animals average less). The tail is short and thick — its plumpness is a health gauge, not a length measure.

About 5–7 years (a maximum around 8 years is recorded).

See a small-animal or exotics vet if you notice: Not eating, or noticeably lethargic; Wheezing, clicking or laboured breathing (often from damp/humid conditions); Sudden weight loss with a thin, shrunken tail; Drooling or difficulty eating (possible overgrown teeth); Bald, sore or wet patches on the skin or tail.
