PetsGuinea pigs are gentle, talkative little animals that rarely bite. They squeak with excitement when they hear food coming. They need company of their own kind, a roomy cage, hay all day and fresh vegetables. They are a good first pet for a family, with an adult in charge.
This is a care guide, not veterinary advice. It covers housing, food, routine and safety. It does not diagnose or treat illness. If your pet seems unwell, is hurt or behaves differently, take it to a qualified veterinarian without delay.

Is a guinea pig right for you?
A good choice if
- You can keep two together
- You can buy fresh vegetables and hay every week
- You want a pet that is awake in the day
- A gentle child will help under supervision
Think again if
- You have room for only a small cage
- You want just one animal
- Your home is very hot or very damp
- Nobody will clean the cage every few days
What you need before the first day
- A large cage with a solid floor
- Two hiding houses, one for each animal
- Paper-based bedding or washable fleece
- Water bottle and heavy food bowl
- Unlimited grass hay and a hay rack
- Guinea pig pellets with added vitamin C
- Fresh vegetables
- A carrier
- Nail clippers
The right home
Guinea pigs need floor space to run, so choose the widest cage you can fit. The floor must be solid: wire hurts their feet. Give each animal a hiding house. Keep the cage indoors, off the floor, away from direct sun, draughts and loud speakers. They should not have an exercise wheel or ball: these strain a guinea pig's back.
Food and water
Like rabbits, guinea pigs need grass hay available all the time. Unlike most animals, they cannot make their own vitamin C, so it must come from food: give fresh vegetables every day, such as capsicum, and pellets made for guinea pigs. Fruit is an occasional treat. Fresh water always.
Never feed
- Chocolate, sweets and bakery food
- Potato, onion and garlic
- Dairy foods and meat
- Rabbit or hamster food as a substitute for guinea pig pellets
- Large amounts of fruit

Handling and behaviour
Sit down before you hold a guinea pig. Scoop it up with one hand under the chest and the other under the hindquarters, and hold it against your body or on a towel in your lap. They startle easily, so move slowly and speak softly. Keep two of the same sex, or ask your vet about neutering, because guinea pigs are lonely alone and breed very quickly together.
When to see a vet
Do not wait and watch if you notice any of these. Go to a qualified vet:
- Not eating or drinking
- Weight falling from one week to the next
- Crusty eyes or nose, or noisy breathing
- Scratching hard or bald patches
- Loose droppings or a dirty bottom
Find a vet before you need one, and keep the phone number where everyone at home can see it. Follow the vaccination and parasite-control schedule your vet gives you.
In India: climate and rules
Guinea pigs suffer in heat and in damp. Keep the cage in a cool, airy room in summer and never in the sun. In the monsoon, change bedding more often and keep hay dry so it does not go mouldy. Fresh capsicum, coriander and other greens from the market should be washed well.
