Fresh food

Fresh food should be the main source of food for guinea pigs, because it contains all the vital vitamins and minerals. A guinea pig needs about 100g – 300g of fresh food every day, no matter whether it is grass, fruits or vegetables.


Grass is an ideal food for guinea pigs but it should always be freshly picked, because otherwise it can ferment, which will cause diarrhoea for the guinea pig. Most herbs like camomile and flowers like daisies or dandelions, that grow among the grass are a welcome change and should be fed as well.

For getting enough fresh food guinea pigs can be kept outside on a lawn. In this case no additional fresh food is needed but it should always be enough hay available.

Other herbs that are healthy for guinea pigs are for example:This is an image of a guinea pig eating grass
