🐹 How to Set Up a Gerbil Habitat (Deep Bedding Is Key)

The gerbil is a cheerful, endlessly busy tunneler, and that single fact drives everything about its home: deep bedding is key. Unlike many small pets, gerbils are built to dig, so the right setup is less a cage and more a "gerbilarium" — a deep tank where they can burrow into a network of tunnels just as they would in the wild.

The gerbilarium

Start with a large glass tank — think 20 gallons or more for a pair — topped with a secure, well-ventilated mesh lid. This tank-style home is far better than a typical wire cage for two reasons: gerbils love to gnaw and will chew relentlessly at cage bars, and, more importantly, a wire cage simply cannot hold the deep bedding they need to burrow. The tank walls also let you watch their tunnel-building from the side, which is one of the real joys of keeping gerbils. Bigger is always better if you have the space.

Bedding & burrowing

Fill the tank with 6 to 10 inches of bedding so tunnels have room to form and hold their shape. A mix of unscented paper or aspen bedding with plain hay or shredded paper works best — the hay and paper act like scaffolding so the tunnels do not collapse. Never use cedar or pine shavings, as their fumes can harm a gerbil's airways. Pop a cardboard tube into the bedding to give them a starting point, and they will take it from there, happily excavating for hours. This deep, structured bedding is the heart of a healthy gerbilarium.

Company

Gerbils are social and should never live alone; keep them in same-sex pairs or small groups. The catch is that introductions matter — gerbils can be territorial, so it is easiest to start with young animals introduced carefully, often using the gradual "split-tank" method so they meet safely through a barrier first. Done right, a bonded pair will groom, sleep, and dig together, and watching their teamwork is half the fun.

Wheel, chews & sand

Gerbils are active by day, so give them plenty to do while you are up to enjoy it. A solid-surface wheel lets them run safely without risk to feet or tails. A shallow sand bath keeps their coat clean and sleek, and it doubles as a fun place to dig and roll. Because their teeth grow continuously, provide plenty of safe wooden chews and cardboard to gnaw — this keeps teeth worn down and healthy while satisfying their instinct to nibble everything in sight.

Feeding

A quality gerbil mix makes an easy, balanced daily staple that suits their desert-adapted appetite. You can offer small amounts of suitable fresh food as an occasional extra, but gerbils naturally eat a fairly dry diet, so keep watery treats to a minimum. Fresh water should always be on hand from a bottle fixed to the tank. Being low-odor, dry-climate animals, gerbils stay remarkably clean and fuss-free.

Quick setup checklist

• Large glass tank (20+ gallons for a pair) with a secure mesh lid
• 6 to 10 inches of deep bedding, plus hay or shredded paper to hold tunnels
• Unscented paper or aspen bedding, never cedar or pine
• A cardboard tube to kick-start their first tunnel
• Solid-surface wheel, sand bath, and wooden chews
• A same-sex pair or small group, introduced carefully while young

With a lifespan of around 3 to 4 years and famously low odor, gerbils make a rewarding, tidy pet — browse our low-maintenance pets guide for more easygoing options, or take our free pet quiz to find your ideal companion.

🧽 Cleaning & maintenance

Spot-clean every day by scooping out soiled bedding, droppings, and leftover fresh food, and rinse the water bottle or bowl. Once a week do a bigger clean: change most or all of the bedding, wipe down the gerbil cage or tank, and scrub the hideouts, dishes, and wheel. Use warm soapy water or a pet-safe small-animal cage cleaner and dry everything before adding fresh bedding — harsh household cleaners and strong scents irritate small lungs. Litter-trained pets make this quick if you scoop the litter box each day.
