Guinea Pig Care Guide: Habitat, Diet and Handling
Guinea pigs are sold as an easy first pet. They are easy to love, but they need more space, more hay and more company than the pet-shop cage suggests.
Two is the minimum
Guinea pigs are herd animals. A single guinea pig is a quiet, nervous guinea pig, and in several countries it is illegal to keep one alone. Get two of the same sex, or a neutered male with a female, from the same litter or bonded by the rescue. They will chatter, groom each other and lie in a heap, which is what a healthy guinea pig looks like.
Introductions between adults can be done but take patience and a neutral space. If you are starting from scratch, a bonded pair from a rescue saves you the trouble and usually comes with the first vet check done.
The cage is too small
Almost every cage sold in a pet shop as a guinea pig cage is too small. A pair needs a floor area of at least 120 by 60 cm, and more is better; guinea pigs do not climb, so height is wasted and floor space is everything. Many keepers build an enclosure from wire grid cubes and a corrugated plastic base, which gives a large footprint for very little money.
Line the base with fleece over an absorbent layer, or with paper bedding; avoid cedar and pine shavings, which irritate the lungs. Add two hideouts so neither pig has to share, a hay rack they can bury themselves in, and a tunnel. Keep the enclosure indoors, out of draughts and direct sun, in a room where the family spends time.
Hay, vegetables and vitamin C
Eighty percent of a guinea pig's diet is hay, and it needs to be available all day, every day. Grass hay such as timothy or meadow hay keeps the gut moving and wears down teeth that never stop growing. A pig that runs out of hay for a day can develop painful dental problems and a slowed gut within weeks.
Guinea pigs cannot make their own vitamin C, so they need it from food. A cup of fresh vegetables per pig per day covers it: bell pepper, leafy greens, a little carrot, the occasional strawberry. Add a small measure of plain pellets fortified with vitamin C, and skip the mixes with coloured bits, which pigs sort for the sugary pieces.
Foods to avoid
No iceberg lettuce, no potato, no onion family, no chocolate, no dairy, no bread. Very little fruit, because of the sugar. Introduce any new vegetable a small amount at a time and watch for soft droppings.
Handling without fear
Guinea pigs are prey animals and being lifted from above feels like a hawk. Sit on the floor, let the pig come to your hand for a piece of pepper, and scoop with one hand under the chest and the other supporting the rear. Hold the pig against your body, never dangling. Keep early sessions short and on the floor, so a wriggle cannot become a fall.
Daily gentle handling turns a skittish pig into one that squeaks at the fridge door and climbs into your lap. It also makes health checks easy: feel the body for weight loss, look at the teeth, check the feet for sores, and run a hand against the coat for scabs or mites.
Vet care and lifespan
A well-kept guinea pig lives five to seven years, sometimes longer. Find a vet who sees small mammals before you need one; not every practice does. The common emergencies are a pig that stops eating, which is always urgent, respiratory infections, and bladder stones. Weigh your pigs weekly on a kitchen scale; a steady loss of fifty grams is the earliest warning you will get of almost anything.
FAQ
Can guinea pigs live outside?
In mild climates, in a well-insulated hutch with a secure run, yes, but they cope badly with heat above 26 degrees and with damp cold. Indoors is simpler and you will see far more of their personality.
Do guinea pigs need baths?
Rarely. A healthy pig keeps itself clean. Spot clean with a damp cloth if needed, and only bath on a vet's advice for a skin condition.
Why does my guinea pig run and jump suddenly?
That is popcorning, and it is joy. Young pigs do it most. A pig that popcorns has enough space and feels safe.
