Gerbils love to dig and are excellent chewers! They therefore require a sturdy enclosure that can hold deep substrate for burrowing, so a tank set-up is really the only option. Hamster cages are not suitable as the bases can be chewed through and they do not provide enough depth for burrowing. You will need at least 8 inches of substrate in your tank for optimum digging potential!

A pair of gerbils should be housed in a tank of at least 75 litres capacity (20 US gallons), but you should seek to exceed this where possible. We strongly advise choosing a 3ft x 1ft x 1ft tank as a minimum. These can be found cheaply on second hand selling sites, and you can just add your own mesh lid. If you want somewhere to easily hang a water bottle you could add a hamster cage or gerbilarium topper on to the mesh lid.

Most gerbilariums sold in pet stores are far too small, however there are a few larger models available online:

DIY options are usually a lot cheaper, unless you can find a good 2nd hand version of one of the above! You can add a mesh lid or use the topper from an unsuitable gerbil cage or hamster cage to add a tank topper.

Safe Substrates

Sawdust and woodshavings (unless the shavings are aspen-based or kiln-dried such as Bedmax/Littlemax) are not recommended as these can cause respiratory issues. Paper, cardboard, or hemp based bedding are suitable alternatives. We have found that mixing in dust extracted meadow hay with cardboard or paper based bedding holds tunnels well.

4 foot tank set-up, with home-made mesh lid

Another excellent DIY option is the Detolf cabinet from IKEA. Laid on its back with a mesh lid added, this makes an excellent tank for gerbils (or hamsters/mice). The example below is our permanent resident mouse/multimammate set-up. With deeper substrate this would be perfect for gerbils
