Rat Digging Box: A Simple, Supervised Setup

Quick decisions at a glance

Why rats love to dig

Digging is natural rat behaviour. The RSPCA points out that wild rats live underground, and says plainly that rats love digging. Pet rats keep the urge to burrow, search for buried food and move material about. A dig box gives that urge a place to go, which is why the RSPCA recommends a box of clean sand or compost for supervised digging outside the cage, and a thick layer of suitable bedding for digging inside it.

Digging also pairs well with foraging. The RSPCA suggests hiding food in sand or gravel trays and cardboard tubes so rats dig or chew to find it, and the PDSA suggests scattering rat nuggets (pellets) around the cage rather than using a bowl. A dig box combines the two. For more ways to keep rats busy, see our 35 rat enrichment ideas and the guide to why your rat is bored.

What can I put in a rat digging box?

Use clean sand, coco coir or a familiar safe bedding. RSPCA UK gives clean sand or compost as examples for supervised digging outside the cage, and recommends suitable bedding for digging inside the cage. Wood Green lists a dig tray with a different substrate, such as coco soil, as rat enrichment. Those examples are not permission to scoop up unknown material from a garden.

What to avoid comes from the RSPCA's and Wood Green's bedding advice: no sawdust or dusty bedding, no aspen, no fragrant or coloured bedding, and no cotton wool or other fluffy materials that separate into strands, which can tangle round limbs or cause harm if eaten. Wood Green also advises against most standard wood shavings. Garden soil and home compost can carry wild animal droppings, chemicals and spoiled food, so they are not worth the risk. Our rat bedding comparison and the guide to the best bedding for rats go through each type.

Check what a product contains and ask your vet if you are unsure it suits your rats, particularly an animal with breathing or mobility concerns. For a simple first activity, a tray of familiar bedding lets you watch the behaviour without introducing several unfamiliar things at once. Don't copy a decorative setup simply because it photographs well. The useful question is whether your rats can investigate the material comfortably and you can keep it clean.

What container works for a rat dig box?

Any sturdy, easy-to-clean container that rats can climb in and out of by themselves works. A plastic storage box with a doorway cut low in one side, a deep cat litter tray, or a large ceramic or metal pan are common choices. Pick one heavy or wide enough not to tip when several rats pile onto the rim.

• Rats can get in and out without being lifted
• Wide and stable, so it won't tip over
• Smooth edges, no cracks or sharp corners (the RSPCA warns against projections that can injure rats)
• Easy to empty, wash and dry
• Room for more than one rat at once, with more than one way in for a group
• Deep enough to bury a treat completely, shallow enough that rats can see over the rim
• A lid or cover if you want to put it away between sessions

Rats chew, so check plastic and card boxes for gnawed edges each time and replace them when worn.

How do I introduce a digging box?

Place the container in your secure free-roam area alongside the rest of the familiar setup. Give your rats a way to approach and leave without being lifted into it. Start simply enough that you can see what happens. A rat that sniffs the edge and walks away has not failed an enrichment test.

1. Choose a familiar filling. Start with the bedding your rats already use, so only one thing is new: the box.
2. Put it on a washable surface. Set the box on an old towel, a shower curtain or a washable mat in the free-roam area.
3. Make the way in easy. Add a low ramp or step if the rim is high, and leave room around the tray so one rat cannot block the only route.
4. Pick the right time. Try when your rats are normally active, usually evening, and keep other changes small.
5. Start with easy finds. Use some of their normal food allowance and leave a few pieces on top or barely covered at first.
6. Hide several pieces. The RSPCA recommends several food items for a group rather than making everyone compete for one prize.
7. Watch, don't place. Let rats find it themselves. Don't put a reluctant rat into the box.
8. Build up. Once they dig confidently, bury food deeper, try a new material, or add a cardboard tube to dig towards.

Rats are naturally cautious, the RSPCA notes, so let them check out the box at their own pace and never force them. The RSPCA also says free roaming should wait until rats are well handled and relaxed. For setting up the room safely, see our rat free roam area guide.

How do I keep it useful rather than messy?

Put a washable protective surface beneath the activity, and keep the box away from electrical cables, unsuitable plants and places you cannot retrieve a rat from. Supervise throughout; a container is not a substitute for rat-proofing the room. Expect some material to be thrown out: that is part of the fun for the rats.

1. Collect the leftovers. After play, take out uneaten food so it doesn't spoil in the box.
2. Sift and spot clean. Remove droppings and wet or dirty patches. A kitchen sieve works well for sand.
3. Replace what can't be cleaned. Throw away damp or soiled material rather than drying it out and reusing it.
4. Store it dry. Keep spare filling in a sealed, dry container. Don't store damp leftovers as if they were dry bedding.
5. Wash the box. Wash and fully dry the container regularly, as you would cage furniture.
6. Write it down. Note which material you used so you can give a precise description if you need advice.

If the activity seems to irritate a rat, or they are reluctant to move normally afterwards, stop and ask your vet rather than adjusting several materials until the signs disappear. For a full cleaning routine for the rest of the cage, see the rat cage cleaning guide.

Can a dig box go inside the cage?

Yes, if you can keep it clean and dry. The RSPCA's in-cage advice is a thick layer of suitable bedding for digging, and Wood Green includes dig trays in its list of rat cage enrichment. Inside the cage, rats may use a dig box as a toilet or a food stash, so check it every day and empty it more often than the rest of the cage. Sand and coir are messier in a cage than in a playpen; paper or hemp bedding in a deep tray is the easier in-cage choice. Our rat cage setup guide shows where everything else goes.
