  5. Diet plan

Hay, vegetables, fruits, branches, herbs and other plant. There is very much you can feed your Guinea Pigs. Cavies listen to their natural instinct and really like to eat what grows on ground – raw. Most of all feed hay! This has to be provided permanent. You do your best to your cavies if you provide fresh picked grass too (please no lawn cuttings!). That is way cheaper than any colorful package of junk food from the pet shop and much more healthy as well. Leave the pet shop food untouched (have a look to the dry food / pellets article)!

Fresh Grass is a great seasonal food for their diet from spring to fall but you have to pay attention if you start to feed grass each year. Start with short amount of it and increase every day a bit. This guarantees that cavies will be softly get into the way of it. At winter season you should replace grass with fresh vegetables to keep them healthy with a diet rich in vitamins. Fruits should be always handled like candy and should not be provided that much. Herbs can be provided fresh or dried permanent in any quantity.

A special highlight for Guinea Pigs are these pants who are outside their accessible area. Small branched from trees and leaves are really liked. But do not aimless cut branches from trees in the wood.
