Guinea pigs should be housed in a hutch, with access to plenty of sunshine (though out of direct sunlight) and fresh air. The minimum size should be 91cm x 61cm x 45cm. It should be around 4-5 times the length of the guinea pig when stretched out. In the winter, guinea pigs should be housed indoors at a temperature between 18-26 degrees celsius.

Place the hutch on bricks to avoid it getting damp in wet weather. Ensure the roof is sloping, waterproof and overhangs slightly. Always ensure the doors are locked.

It’s important to have fresh safe bedding and to clean the hutch out regularly to avoid attracting flies. Flies can lay eggs, leading to an infestation of maggots. In the winter, bedding can become damp and mouldy.


Guinea pigs need a balanced diet of specially formulated guinea pig food and hay daily. The food must include vitamin C as guinea pigs cannot generate their own and will become ill without it. Hay provides fibre and helps wear down their continuously growing teeth. We recommend a mono-component diet (where all the ingredients are mixed into biscuits) to avoid selective feeding. A water bottle should also be provided to keep the water fresh.

Treats should only be given occasionally and should be specially designed for guinea pigs as some human foods can be poisonous for them.


Guinea pigs are frightened in large open spaces and love to hide in tunnels and boxes. They also like to have access to wood, so they can keep their teeth in trim.

Handling Your Guinea Pig

Talk to your guinea pig and approach it at the same level. Let it come to you and sniff your hand. Gently place your hand across its shoulders and slowly lift it up, placing your other hand under its rump to support it. Either place it in your lap or hold it close to your chest while getting up.


Guinea pigs are sociable and should be housed with other guinea pigs. Female pairs are fine. Males live happily together but may become agitated in the vicinity of females. If females and males are housed together they must be neutered to avoid litters.
