What Can Guinea Pigs Eat?

Guinea pigs can eat a variety of vegetables and fruit but remember that hay and pellets should form the major part of their diet. Fruit should be a very occasional treat.

Our guinea pig fruit and veg list tells you which foods are safe for your cavies to eat including nutritional values and how regularly they can be fed any particular food.

Foods high in oxalic acid should not be given in large quantities but they do need plenty of vitamin C in their diet. Find out more about the different types of food that guinea pigs need.

Feeding Tips and Advice

Here are some points to remember when feeding vegetables and fruit to your guinea pigs:

  • Although vegetables should be fed daily, don't give them too much as it could result in diarrhoea and obesity
  • Fruit must only be given in very small quantities and very occasionally
  • Always wash fruit and vegetables thoroughly before serving to get rid of any nasties like pesticides
  • Guinea pigs love lettuce but Iceberg is not suitable as it has very little nutritional content and can result in loose stools
  • They can be fussy pets but they can get a taste for something if you persist in small amounts
  • There are certain foods that are poisonous for guinea pigs. Click here to view the dangerous foods
