Guinea pig enrichment: toys and boredom busters

Why guinea pigs need enrichment

Guinea pigs are awake and active day and night, taking short naps rather than one long sleep, and in the wild they spend that time grazing, exploring and hiding together. A bare cage gives them nothing to do. The Humane World for Animals says guinea pigs can become bored and depressed without enough stimulation, and the RSPCA describes them as intelligent animals that enjoy gnawing, chewing and exploring.

Good enrichment is not about buying lots of toys. It is about letting a guinea pig do what it is built to do: run, hide, chew, forage and talk to other guinea pigs. Every item below serves one of those.

Signs your guinea pig is bored or stressed

The RSPCA lists these behaviours as signs a guinea pig may be distressed, bored, ill or injured:

• Hiding most of the time
• Chewing the cage bars
• Repeatedly chewing the water bottle, or drinking much more than usual
• Over-grooming, sometimes with bald patches
• Aggression towards people or cage mates
• Repeatedly circling the enclosure
• Sitting hunched or not wanting to move
• Changes in eating or toilet habits

Several of these can also mean pain or illness, so if a change comes on suddenly, see a vet before assuming it is boredom. Our guide to guinea pig behaviour explains what normal looks like.

Enrichment toys for guinea pigs: what actually works

The toys that work best are the ones that let guinea pigs hide, tunnel, chew and search for food. These are the main types, drawn from RSPCA, PDSA and PetMD advice:

The RSPCA says to give untreated wooden toys and avoid plastic ones, which may harm guinea pigs if chewed or swallowed. Keep ramps low and gentle: the Humane World for Animals notes that guinea pigs do not jump or climb, and PetMD warns that falls can injure their backs. For our picks, see our list of the best guinea pig toys and the best guinea pig hides.

Oxbow toys for guinea pigs

Oxbow, the hay and pellet maker, sells a range of guinea pig enrichment called Enriched Life. Items listed for guinea pigs include the Burrow Box, the Apple Stick Bundle, the Apple Stick Hay Feeder, the Apple Twig Tree, the Bamboo Ball Pit and the Bamboo Play Pouch. The Burrow Box is made of corrugated card, willow bark and paper and is sold for foraging, nesting and hiding.

Oxbow suggests putting a variety of chews and play items in the enclosure every day. You do not need a brand to do that, but ready-made pieces save time and are made for small plant-eaters. Whatever you buy, check that a hide has an opening big enough for an adult guinea pig to turn round in, and that there are no small loose parts.

DIY enrichment for guinea pigs

Most of the best enrichment costs nothing. The RSPCA suggests shelters made from cardboard boxes or tubes, and PetMD suggests tissue boxes and toilet roll tubes stuffed with hay.

1. Make a hay tube. Stuff a toilet roll or kitchen roll tube with hay and push a few pellets or a herb sprig into the middle.
2. Build a box hide. Cut two doorways in opposite ends of a plain cardboard box, big enough for an adult to walk through, and fill the floor with hay.
3. Make a forage box. Fill a shallow box or tray deep with hay, then scatter in the day's pellets and some chopped greens.
4. Hang greens. Peg a bunch of coriander or dark lettuce at nose height so they have to stretch and pull for it.
5. Make a tunnel run. Line up two or three boxes with doorways cut between them to make a route they can run through.
6. Check and replace. Remove tape, staples and plastic windows first, and throw cardboard away once it is soggy or soiled.

Foraging: make every meal a game

Foraging is the easiest enrichment there is, because guinea pigs already spend most of their waking time eating. PDSA suggests scattering pellets around the enclosure instead of using a bowl. Woodgreen says to spread hay across the whole enclosure, the run, and under hides. The RSPCA suggests scattering a forage mix into the bedding.

Start simple: put hay in two or three places rather than one, hide the pellet portion in a hay pile, and tuck a strip of pepper under a hide. Food guidance stays the same whatever the game, so check our guinea pig diet guide for daily amounts.

Floor time, space and play

Space is enrichment in itself. The Humane World for Animals calls a larger enclosure one of the most basic types of enrichment, because it lets guinea pigs exercise when they choose. Young guinea pigs need room to do their frisky hop, often called popcorning, and the RSPCA says that needs a height of around 30 cm (12 in).

On top of a good home, give time outside it. PetMD's care sheet says at least one hour of exercise outside the enclosure every day, with wires and gaps out of reach. PDSA says an outdoor run should be at least 2 × 1 m (6.6 × 3.3 ft), on grass without mud or standing water, and that temperatures above 24°C (75°F) can be uncomfortable. Indoors, use a non-slip, easy-clean floor. Our guides to floor time and playpens and guinea pig cage size have the details.

Is another guinea pig the best enrichment?

Yes. No toy replaces company. The RSPCA says guinea pigs should live with at least one other friendly guinea pig, and the Humane World for Animals says a single guinea pig can become lonely and bored even if its owner spends a lot of time with it. Pairs groom each other, talk constantly, follow each other and play together. If yours lives alone, our guide on pairs and groups explains how to find and introduce a friend.

Unsafe toys and setups to avoid

• Exercise wheels and balls: none of our sources recommend them, and guinea pigs are built for running on the flat
• Plastic chew toys, which the RSPCA says can harm them if chewed or swallowed
• Painted, varnished or treated wood
• Hides and tunnels with only one exit
• High shelves, steep ramps or hammocks they could fall from
• Cables and cords within reach during floor time, as PetMD warns
• Houseplants and garden flowers they could nibble
• Toys with bells, string or small parts that could come loose

A simple weekly enrichment rotation

Keep the main hides where they are, so your guinea pigs always know where safety is, and rotate the rest. Each week, swap one tunnel or box for a different one, change where the hay piles go, add one new chew, and try a new foraging game. PDSA reminds owners to clean toys and shelters as well as the cage. For how to lay it all out, see our guinea pig cage setup guide, and for everything else, the complete guinea pig care guide.
