Guinea pig: gear and buying guides
The guinea pig is a highly social, diurnal rodent that must live in pairs at the very least: a lone animal becomes depressed. It communicates through a rich range of whistles and loves routines, especially vegetable time. Group living and its size call for an enclosure far larger than most pet-shop cages.
Profile : Around 20 to 30 cm and 700 to 1,200 g, a lifespan of 5 to 8 years, and a gentle, expressive temperament that rarely bites.

Guinea pig gear, family by family
-
🍖
Food
Unlimited hay (80 percent of the diet), daily fresh vegetables and a small amount of pellets. Like humans, it cannot make its own vitamin C: a daily intake of roughly 20 to 30 mg from rich vegetables or a supplement is vital.
-
🧴
Care & grooming
Nail trims every 4 to 6 weeks, regular brushing for long-haired breeds, and weekly teeth and weight checks. Change the bedding often: guinea pigs urinate a lot.
-
🎾
Toys & enrichment
Tunnels, hideouts, hay stuffed into foraging toys and hazel branches to chew. No wheel and no exercise ball: its spine is not built for them.
-
🏠
Bedding & habitat
An enclosure of at least 120 x 60 cm for two, ideally an indoor pen of 2 square metres or more. A solid floor covered with bedding or fleece, and one hide per animal to prevent squabbles.
-
🧳
Travel & safety
A rigid small-animal carrier (15 to 30 euros) lined with hay; transport cage-mates together to reassure them. Sensitive to heat: never leave one in a car in full sun.
-
🧰
Accessories
A hay rack, duplicated water bottles or heavy bowls, nail clippers and a brush. Plan 150 to 300 euros of setup for a pair, then weekly hay and vegetables.
🧴 Care for a Guinea pig: healthy bedding and prevention
Self-grooming, gently assisted
The Guinea pig grooms itself and never gets a water bath, apart from spot-cleaning with a damp cloth. Your job: clean, dust-extracted bedding free of essential oils — never cedar or untreated pine shavings, documented respiratory irritants.
Habitat upkeep: your real mission
The toilet corner gets cleaned every two days, full bedding changes happen weekly or fortnightly depending on floor area, and accessories are washed in hot water without fragrance. Smell is the Guinea pig’s primary sense: scented disinfectants stress it more than they reassure you — and always keep back a handful of old bedding to preserve its scent map.
Health signals specific to the Guinea pig
Documented watch-points: scurvy (vitamin C deficiency) and dental malocclusion. As prey animals, rodents hide their symptoms: weigh weekly (weight loss speaks before they do) and see an exotics vet at the first doubt. Life expectancy: 5 to 8 years.
Quick answers
- Should you wash a Guinea pig?
- No: it grooms itself. Clean bedding and a healthy environment replace any shampoo — water only brings stress and chilling.
- Which bedding for a Guinea pig?
- Hemp, flax or dust-extracted paper; never cedar shavings or scented litters. A 5 to 10 cm layer covers burrowing and comfortable movement.

🎾 Enrichment for a Guinea pig: space and foraging
Why no wheel for the Guinea pig
Unlike hamsters, the Guinea pig does not use a wheel: its stocky build and rigid spine get injured on one. Its exercise is surface area: clear runways, solid levels and outings in a secure pen.
Digging and burrowing: its real talents
The Guinea pig finds its enrichment at ground level: deep bedding to dig, cork or cardboard tunnels, hay to rummage and multiple hideouts. Closed plastic “modular habitat” tubes are best avoided: poorly ventilated and quickly chewed through.
Working with its body clock
The Guinea pig is diurnal — active on your schedule: make the most of regular daytime interaction; it learns routines fast. Companions remain its first enrichment: no toy replaces social life.
Quick answers
- Does a Guinea pig need a wheel?
- No — it is actually discouraged: its build gets injured on one. Provide floor space and pen outings instead.
- Can a Guinea pig live alone?
- No: the species is social: group life (or at least a pair) is a need, not an option. An isolated individual develops stress and behavioural problems.
