DIY Enrichment Toys for Small Pets: Four Practical Ideas

By Dr Duncan Houston

A cardboard box can offer a small pet somewhere to hide, investigate or search for food. The useful part is the opportunity to choose an activity, rather than how elaborate the finished toy looks.

Rabbits, guinea pigs, chinchillas, hamsters and ferrets have different diets and ways of playing. These projects explain which animals they suit, how to reduce avoidable hazards and when to choose something simpler.

Quick Answer

Simple DIY enrichment can include open hay troughs, easy paper food parcels, roomy cardboard hideouts and foraging boxes. Use clean, plain materials, offer only food appropriate for that species from its usual ration, and supervise each new design. No homemade toy is safe for every animal: remove it if your pet gets trapped, eats the construction materials or becomes distressed, and keep ordinary food, water and resting places accessible.

Match the activity to your small pet

Animal	A useful starting point	Food and welfare limits
Rabbits	Hay foraging, digging and spacious boxes with multiple exits.	Use their usual hay and a few pellets from their measured ration. Keep their main hay supply available. See the RSPCA's rabbit toy ideas.
Guinea pigs	Low entrances, sheltered routes and easy hay searches.	Keep familiar hay, species-specific pellets and their normal vitamin C provision. A puzzle must not displace the guinea pig's balanced daily diet.
Chinchillas	A low hay trough or roomy hideout, watched closely for material consumption.	Use usual hay and chinchilla pellets. Skip fruit and sugary fillings; PDSA's chinchilla diet advice explains why hay and restrained treat feeding matter.
Hamsters	Easy food searches, shreddable paper and opportunities to burrow.	Use a small portion of their normal complete hamster food. Offer activities when they are awake, as described in PDSA's hamster care guidance.
Ferrets	Roomy exploration routes and a simple search for familiar food.	Ferrets are carnivores. Use their usual suitable ferret food, rather than hay, seeds or fruit as rewards. The MSD Veterinary Manual's ferret guidance also advises against hay and wood shavings as bedding.

These animals should have separate, species-appropriate play areas. Ferrets must not join rabbits or rodents for enrichment sessions.

Check materials and openings before building

Choose known, clean materials. Use plain, uncoated cardboard or unscented paper. Reject packaging with grease, chemical residues, mould, glitter, foil, plastic lining or a strong smell.
Remove attachments completely. Take off tape, labels, staples, handles and exposed adhesive. Do not add glue, string, ribbon, wire, elastic bands or skewers. These designs do not need fasteners.
Leave uncertain materials out. Avoid foam, rubber, fluffy cotton-like filling and unidentified or treated wood. “Natural” does not establish suitability for chewing or swallowing.
Make openings generous. An animal must pass its whole body through freely, with extra room for a hamster's filled cheek pouches. Allow room to turn inside boxes. Do not use tight neck holes, small decorative windows or closed cardboard rings.
Keep everything at floor level. Use stable boxes on a non-slip surface. Do not stack them into climbing towers or place them beside enclosure walls where they create an escape route.

Ferrets need particularly close observation around chewable objects. The MSD Veterinary Manual's ferret safety advice identifies swallowed foam, rubber and plastic as choking and intestinal blockage hazards. A ferret that consumes cardboard should have a food search on a clean floor instead of a cardboard project.

Four DIY enrichment projects

1. An open hay trough for rabbits, guinea pigs or chinchillas

Take a plain cardboard tube and cut it all the way along its length. Open it out into a broad trough, so no enclosed ring remains. Discard it if the edges are rough or it keeps curling tightly closed.
Lay a loose handful of the animal's usual hay across it. Leave hay easy to grasp without pushing the head into an opening.
Add a few usual pellets if wanted, deducted from the daily portion, and place it on the floor.

This adapts the rabbit hay-tube idea into an open design. For guinea pigs, a shallow hay-filled box is another option; the RSPCA's guinea pig housing guidance supports sheltered exploration and foraging. For chinchillas, use this only while supervising and remove it if cardboard is being eaten. The RSPCA's chinchilla environment advice includes cardboard enrichment and hay-filled hiding places.

2. An easy paper parcel for a hamster

Put a little of the hamster's normal dry food on a small sheet of plain, thin, unscented paper.
Fold one edge loosely over part of the food. Keep some food visible and leave the parcel open at the sides.
Set it beside a familiar sheltered route while the hamster is awake. Let the hamster sniff, uncover or shred it without being handled.

If the hamster cannot obtain the food easily, open the paper fully. Food must remain available elsewhere. The RSPCA's hamster feeding advice supports hiding or scattering food to encourage foraging; start with an easy version.

3. A two-exit cardboard hideout

Choose one box large enough for the intended animal to stand and turn comfortably. Remove loose flaps and all packaging attachments.
Cut two broad doorways on different sides, with smooth edges and low thresholds. Never close the animal inside.
Place the box in the usual secure exercise area. Add a second separate box later if your pet enjoys exploring, leaving clear space between them.

The RSPCA recommends more than one opening in rabbit hiding places. This design also gives guinea pigs an easy route through, while larger boxes can provide supervised exploration for ferrets. Veterinary ferret enrichment guidance from The Unusual Pet Vets stresses that tunnels must be wide enough to prevent trapping.

For pets with arthritis, limited vision or restricted movement, keep the route short, entrances wide and food within easy reach. Follow postoperative activity restrictions rather than encouraging climbing or vigorous digging.

4. A simple digging or foraging box

Choose a broad, stable box with a low entrance and no lid.
For a rabbit, add loose plain shredded paper for digging. For a guinea pig or chinchilla, make a shallow search area using their usual hay.
For a hamster, use familiar, dust-extracted paper bedding and scatter a little usual dry food near the surface. This activity supplements the deep burrowing bedding in its main enclosure.
Start with rewards visible. Make them only slightly harder to find once the animal participates comfortably.

Do not add scented litter or fibrous fluffy filling. The RSPCA's hamster bedding guidance warns that thin-stranded nesting materials can entangle limbs and cause harm if eaten. Skip this hay-based project for ferrets.

How can you tell whether enrichment is working?

What you observe	What to do
Voluntary sniffing, searching or resting, with normal eating	Let your pet choose how long to participate. Quiet exploration counts.
Repeated retreat, freezing or difficulty reaching food	Stop the challenge. Offer an open, easier version near familiar cover later.
Another animal blocks access	Provide separate activities and clear escape routes within the established compatible group.
Material consumption, snagging, unstable cardboard or sharp damage	Remove the item immediately. Seek veterinary advice if there is injury or suspected ingestion of a hazardous piece.

What if your pet will not play?

A new object may be unfamiliar, the task may be too difficult, or the animal may simply prefer another activity. Try an empty hideout or a few familiar food pieces in the open. Do not wake a sleeping animal or withhold meals to create interest.

A sudden loss of interest alongside reduced eating, drooling, fewer droppings or reluctance to move needs veterinary assessment. Dental pain, digestive illness or mobility problems can make an apparently easy task uncomfortable. Contact your vet immediately about reduced eating or droppings in a rabbit, guinea pig or chinchilla. Do not wait for a different toy to restore appetite.

If any animal has breathing difficulty, collapses or appears to be choking, seek emergency veterinary care immediately. Suspected swallowing of string, rubber, plastic or a substantial toy fragment also warrants an immediate call to a vet.

Your first-session action plan

Choose one easy project matched to your pet's species and physical abilities.
Check every surface and opening before putting it down. Keep familiar food, water and shelter accessible.
Stay nearby throughout the first session. Let your pet approach and leave voluntarily.
Inspect the toy afterwards and at least daily if it remains available. Discard damp, dirty, collapsing or hazardous cardboard straight away.
Refresh one activity when interest fades, while retaining familiar resting places and routes. Record any change in appetite or droppings.

Common mistakes to avoid

Adding treats on top of the normal ration every time a toy is refilled.
Using tightly packed or sealed food puzzles before an animal understands the task.
Assuming a small head means the body will fit through the same hole.
Leaving damaged toys until a scheduled weekly clean.
Expecting crafts to replace exercise space, appropriate social housing, rest or a suitable diet.

Frequently asked questions

Are toilet roll tubes safe for small pets?

They can be used in some enrichment designs, but size, cleanliness and the animal's behaviour matter. For the hay project above, cut the tube fully lengthways and open it into a trough. Avoid scented tubes and remove cardboard if your pet eats it.

Can I use glue or string for homemade pet toys?

These projects need neither. Leave glue, tape, strings and hanging loops out of the design, and reject packaging if attachments or adhesive cannot be removed completely.

Do homemade chew toys prevent dental disease?

No toy guarantees healthy teeth. Rabbits, guinea pigs and chinchillas still need their appropriate hay-based diets. Drooling, altered chewing or reduced appetite needs a veterinary check, even when plenty of toys are available.

How often should I replace cardboard enrichment?

Replace it according to its condition, not a fixed calendar. Check before use and daily while available; discard it as soon as it is wet, soiled, unstable or developing trapping hazards.

Start with a choice your pet can enjoy

One accessible, well-observed activity is enough to begin. Keep the diet familiar, make escape and food access easy, and judge success by comfortable, voluntary participation. If your pet's usual behaviour changes, check their health as well as the toy.
