The Guinea Pig is a small mammal native to the Andes region. It is a so-called restrict herbivore that requires vitamin C supplementation.
Its diet is based on the consumption of hay and vegetables at will, to be integrated with Fortified Foods, also known as pellets or feed, specific for guinea pigs that contain stabilized vitamin C. The hay also favors the abrasion of the teeth, which never stop growing in these little furry ones. Always provide clean water.
Absolutely to avoid carbohydrates.
