There is a huge variety of plant you can feed your Guinea Pigs with. They are really vegans and like nearly everything which grows on ground.

What do Guinea Pigs like to eat

Hay, vegetables, fruits, 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. That is way cheaper than any colourful package of junk food from the pet shop and much more healthy as well.

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.

 Three Things Your Guinea Pigs Need

  • Your pets need constant access to good quality grass or hay and this means both day and night. In order to maintain a healthy digestive system and strong healthy teeth, guinea pigs need to be chewing on either or both of these whenever they want to
  • You need to offer about a teacup of fresh greens to each of your guinea pigs every day – so they get all the nutrients and vitamins out of them
  • You need to feed your guinea pigs some good quality guinea pig nuggets – make sure you follow the guidelines on the packet as to how much to feed them on a daily basis

What to Avoid Feeding Your Guinea Pigs

Avoid feeding any muesli-type mixtures because you will end up with lots of bits left over. Your pets will eat the tastier bits, usually the sweeter ones and leave anything they don’t like, these are usually the healthy bits that are full of fibre. A lack of fibre in a guinea pigs’ diet leads to painful dental diseases.
