Feeding guinea pigs
Guinea pigs are vegetarians who like grass and plants. High-quality hay should be the main part of the daily diet.
The hay must be green, dry and dust-free. In the summer months, they can also get fresh grass and fresh plants such as dandelions and plantains. It is important that you introduce this gradually in the spring, otherwise the animals can have serious stomach problems. Hay and green fodder that is moldy can make the guinea pig sick.
In addition to hay, the guinea pig should receive a feed mixture that is adapted to the species. Guinea pig pellets with added vitamin C are recommended. Guinea pigs have a voracious appetite and quickly become fat if they are given too much nutritious food. One to two tablespoons of pellets daily is enough for a guinea pig in normal conditions.
Guinea pigs do not have the ability to produce vitamin C themselves and therefore need this added to their diet to stay healthy. You can do this by feeding them daily with vitamin C-rich vegetables, such as peppers and broccoli.
Fruit and salad can be given occasionally as a treat. Guinea pigs can eat most types of fruit and vegetables with the exception of onions, potatoes, potato and tomato plants, avocados and stone fruits. New food must be given in small portions, so that the guinea pig gets used to it gradually. Abrupt changes in the diet can give the animal stomach problems.
It is important that there is always plenty of hay and other things to gnaw on in the cage. A lack of hard food can cause problems with overgrown teeth. You can give the guinea pigs fresh, unsprayed branches from fruit trees with leaves and buds.
Guinea pigs drink little water if they are fed a lot of greens and little dry food, but animals must always have access to fresh water.
