“The best enrichment toys match each rodent’s natural behaviors: solid wheels, deep bedding, and dig boxes for hamsters, gerbils, and mice; hammocks, ropes, and foraging puzzles for rats; tunnels, hay piles, and hideouts for guinea pigs; and ledges, chews, and dust baths for chinchillas and degus. Many of the best toys are free, like cardboard boxes and paper.”
Enrichment means giving animals opportunities to do what comes naturally: dig, forage, climb, chew, hide, and explore. For pet rodents living in a cage, enrichment is the difference between a bored, stressed animal and a curious, active one. You don’t need to spend a lot. The key is choosing items that fit your pet’s species and rotating them to keep things interesting. This guide covers what works for each common pet rodent. We focus on types of toys rather than specific brands.
Enrichment by Species
| Species | Top Enrichment | Avoid |
|---|---|---|
| Hamsters | Large solid wheel, deep bedding, scatter feeding, multi-chamber hides | Small or mesh wheels, hamster balls |
| Gerbils | Deep bedding, cardboard to shred, sand bath, wheel | Plastic toys |
| Mice | Climbing ropes, wheels, nesting material | Wide-barred cages |
| Rats | Hammocks, ropes, foraging puzzles, dig boxes, training | Being kept alone |
| Guinea pigs | Tunnels, hay piles, fleece forests, floor time | Wheels, balls, climbing structures |
| Chinchillas | Ledges, wood chews, dust baths, playtime | Plastic, hot rooms |
| Degus | Wheels, chews, sand baths, dig boxes | Plastic, sugary treats |
Wheels
Wheels are essential for hamsters, gerbils, mice, and often degus and chinchillas. Choose a solid running surface, never mesh or rungs, and make sure it’s large enough that your pet’s back stays straight:
- Syrian hamsters: 11 to 12 inches
- Dwarf hamsters, gerbils, and mice: 8 inches or more
- Degus: at least 12 inches
- Chinchillas: at least 15 inches, metal only
Guinea pigs and rats should not use wheels; their body shapes aren’t suited to them.
Digging and Burrowing
For hamsters, gerbils, and mice, deep bedding is the best enrichment of all. Aim for 6 to 10 inches or more. Add a dig box filled with a different substrate, like coconut fiber, plain soil, or shredded paper, for variety. Rats also love dig boxes filled with shredded paper or pesticide-free soil with treats hidden inside. See bedding comparison.
Foraging Toys
In the wild, rodents spend hours searching for food. Recreate that with:
- Scatter feeding: spread dry food around the enclosure instead of using a bowl.
- Paper balls: wrap treats in plain paper.
- Stuffed tubes: fill cardboard tubes with hay and a treat, then fold the ends.
- Egg cartons: hide treats in each cup and close the lid.
- Puzzle feeders: sliding or lifting puzzles made for small animals, especially good for rats.
- Hay racks: make guinea pigs and chinchillas work a little for their hay.
Chews
All rodents need safe things to gnaw on to keep their ever-growing teeth healthy. Good options include untreated apple, willow, or pear wood; cardboard; hay cubes; loofah; and pumice stones for chinchillas and degus. Avoid cedar, pine, cherry, and treated or painted wood. See rodent anatomy.
Climbing and Exploring
- Rats and mice: ropes, ladders, hanging bridges, branches, and multiple shelves.
- Chinchillas and degus: sturdy wooden ledges at different heights for jumping.
- Hamsters: low platforms and cork logs; avoid tall structures they could fall from.
- Guinea pigs: keep everything at ground level with gentle ramps only.
Hides and Tunnels
Hiding spots help prey animals feel safe. Offer multi-chamber hides for hamsters, cork logs and wooden houses for gerbils and mice, fabric tunnels and fleece forests for guinea pigs, and hammocks and cube beds for rats.
Sand and Dust Baths
Gerbils, dwarf hamsters, and degus enjoy sand baths, while chinchillas need fine dust baths. Rolling is both grooming and play. See chinchilla dust baths.
Social and Mental Enrichment
For social species, the best enrichment is a companion. Rats, guinea pigs, gerbils, degus, and female mice all benefit from living with their own kind. See social vs solitary rodents. Training is another form of enrichment, especially for rats. See how to train a pet rat.
Out-of-Cage Time
Supervised playtime in a safe area lets pets explore new sights and smells. Rats, guinea pigs, chinchillas, and degus especially benefit. Set up tunnels, boxes, and hidden treats in a playpen or rodent-proofed room. See rodent-proofing your home.
Free and DIY Enrichment
- Cardboard boxes with holes cut for doors
- Toilet paper and paper towel tubes
- Plain, unprinted paper for shredding and nesting
- Paper bags (handles removed)
- Safe branches from untreated fruit trees
- Hay-stuffed boxes
Avoid glue, tape, glossy printing, and anything with small parts. Check out our holiday rodent crafts for seasonal DIY gift ideas for pets.
Toys to Avoid
- Exercise balls: many experts discourage them because pets can’t control them well or escape if frightened.
- Mesh or rung wheels: cause foot and tail injuries.
- Cotton fluff bedding: can wrap around limbs or block intestines.
- Soft plastic toys: easily chewed and swallowed.
- Salt and mineral licks: generally unnecessary with a balanced diet.
- Yogurt-covered or sugary chews.
Rotate to Keep It Fresh
Change a few items each week so the environment stays interesting. Rodents love novelty, but too much change at once can be stressful, so rotate gradually.
Why Enrichment Matters for Health
Enrichment isn’t just about fun. Research on laboratory and pet rodents has shown that animals living in enriched environments tend to be less stressed, more active, and more resilient than those in bare cages. They show fewer repetitive stress behaviors like bar biting and pacing, and they’re often calmer when handled. Active pets are also less likely to become overweight. In short, a stimulating home supports both mental and physical health, and it makes your pet more fun to watch and interact with.
Signs Your Pet Needs More Enrichment
- Bar biting or chewing on cage walls
- Pacing, circling, or repetitive flipping
- Overgrooming or fur loss
- Lethargy and lack of interest in surroundings
- Weight gain
- Escape attempts
Frequently Asked Questions
What toys do hamsters like?
Large solid wheels, deep bedding for digging, hides, and foraging opportunities.
Do rats need toys?
Yes. Rats are intelligent and need climbing, foraging, and social enrichment.
Can guinea pigs use a wheel?
No. Wheels can injure a guinea pig’s back.
Are hamster balls safe?
Many experts discourage them. A large enclosure and a proper wheel are better.
