Gerbil Care for Beginners

🐭 The short version: gerbils are the desert diggers of the pet world — tireless little burrowers that build tunnel systems, gnaw everything, and bond into tight family “clans.” They’re clean and nearly odourless, but they come with two catches: they need a deep gerbilarium to dig properly, and their clans can dramatically fall apart (declanning), so you have to watch the social side.

Housing: a gerbilarium, not a cage

Gerbils need a gerbilarium rather than a standard cage: large, with solid glass or plastic walls, a secure wire-mesh top, and a solid floor — deep enough to hold a thick bed of substrate. Barred cages aren’t recommended, because gerbils can injure their legs on the bars and gnaw them (damaging their teeth). Aim for around 50 cm of height with 20–30 cm of bedding, so they can dig proper burrows and still stand fully upright above ground. Use a mix of rough-grained woodchips and hay, plus shreddable material (ink-free cardboard, plain paper, toilet-roll tubes). Include a stone or rough surface to help wear their claws down.

Spot-clean every few days and deep-clean only every two to three weeks — over-cleaning destroys their scent and burrows.

Company — and declanning

Gerbils are clan animals (wild groups run from two to fifteen) and must never be kept alone. Keep them in same-sex pairs or groups formed early in life and kept stable — don’t add an adult stranger later (established clans rarely accept newcomers, except juveniles under about five weeks, introduced gradually through a split cage).

The thing to watch is declanning: a settled clan can suddenly turn on each other. Check daily for fresh wounds or a gerbil being driven away, and be ready to separate them permanently if it happens.

And a hard rule: never pick a gerbil up by its tail — the skin can slip off, exposing the bone (tail slip). Always scoop them up in cupped hands.

Temperature

An ideal range is about 20–24°C. Keep them out of direct sun and away from damp and draughts; they’re desert animals but still need a stable, comfortable room temperature.

Diet

A good-quality food made specifically for gerbils — a compound pellet or a proper seed mix — as the base. Supplement with small amounts of fruit (pear, melon, apple) and vegetables (cucumber, carrot, pumpkin) as part of the ration. Avoid too many fatty seeds like sunflower (they cause obesity), and never give grapes or rhubarb, which are poisonous to rodents. Provide fresh water at all times.

Health

Gerbils are prone to epilepsy — a brief seizure or trance-like episode is usually harmless but worth mentioning to your exotic vet. Also see a vet for a red, crusty nose (nasal dermatitis, often stress-related), diarrhoea with a hunched posture, any lump (especially on the belly scent gland in older gerbils), sudden fighting, or an injured tail.

The honest takeaway

Give gerbils a deep tank and a stable clan and they’re some of the most entertaining, low-odour, low-maintenance small pets around — endlessly busy engineers you can watch for hours. See the full gerbil care guide for the complete spec.
