Unsafe Foods for Guinea Pigs

Your guinea pig’s tummy is quite delicate and if you feed your piggy the wrong types of food it can cause serious health problems such as diarrhoea.

There are some foods that are bad for your guinea pig and others that are actually poisonous

Remember that your cavy is vegan. They don’t eat any animal products or by-products of animals.

List of Foods & Plants that are Poisonous or Dangerous for Guinea Pigs

  • Animal matter in any shape or form
  • Any snack made for a human
  • Bindweed
  • Buttercups
  • Celandine
  • Cereal
  • Chocolate (very dangerous)
  • Citrus Fruit (the acid can cause problems with their sensitive tummies)
  • Dairy produce of any kind
  • Deadly Nightshade
  • Dock Leaves (young ones are supposed to be ok but it is unadviseable to feed them these just in case)
  • Flowering plants
  • Foxgloves
  • Grain
  • Honeysuckle
  • Horse Chestnut
  • Houseplants
  • Nuts
  • Onion (or onion-related vegetables)
  • Poppies

  • Seeds and pips found in fruit (particularly apples)
  • Sorrel
  • Sugar
  • Tomato leaves (the tomato fruit is safe)
  • Unidentified weeds

There are sure to be other items that aren’t included above so always check before giving them something new. We have a safe food list for guinea pigs that you can refer to.

Guinea Pig Treats

Before buying treats that are labelled suitable for guinea pigs, do check the ingredients. It’s surprising how many contain seeds and grains which are unsuitable for your cavy. 

Some of these treats may also contain mealworms which are not suitable either as they are a form of meat.

Fresh Fruit

Certain fresh fruits can be fed to your cavy but should only be given as a very occasional treat. When you do offer this to your guinea pig, always make sure that you remove any seeds and pips because they will not be able to digest these and, in the case of apple seeds, can be dangerous.
