Fresh foods for Rabbits and Guinea Pigs

Provide a variety of different types of vegetables and fruits daily.

We recommend you give your small pet three to six different types of fresh items per day, with more vegetables than fruits as the sugar content of fruits make them unhealthy in large amounts.

How much should I offer?

Vegetables, herbs, weeds, etc

  • An average rabbit should have approximately 2 cups of vegetables per day.
  • Guinea pigs should be offered ¼ cup a day.
  • Wash herbs and leafy greens before giving them to your pet.


Fruits are high in sugars, so these should only be offered as a treat.

  • An average rabbit should be offered a maximum of 2 tablespoons of fruit per day.
  • An average guinea pig should be offered a maximum of 1 tablespoon of fruit a day.
  • Make sure to remove pits from fruits e.g. apricot, cherries, plums.
  • You can leave the skin on the fruit.

Branches, leaves or flowers

Branches help prevent overgrown teeth, but check which are safe for rabbits and guinea pigs.

  • Willow, spruce, ash (tree), maple (sugar and silver), juniper, poplar, apple, pear, hawthorn, hazel and citrus trees are all safe branches for rabbits to chew on.
  • Always provide these in moderation. Too much can be unhealthy.
  • Steer clear of branches with stone fruit as these are toxic (e.g. apricot, plums, cherries, peach, nectarines)

Guinea pigs

Guinea pigs, like us, do not produce vitamin C, so need to have it supplied in the diet each day.

The average, non-breeding, healthy guinea pig will need 25mg/kg of Vitamin C each day. Breeding or unwell animals should be given 50mg/kg.

You should include a Vitamin C-containing food in your guinea pig’s fresh food allowance every day.

Sources of vitamin C mg of Vitamin C per cup

Cabbage leaves
Turnip greens
Broccoli florets
Strawberries 100
Kale 192
Mustard greens
Brussel sprouts
Broccoli leaf

A Vitamin C calculator for guinea pigs can be found here.

Guinea pig mix has good levels of Vitamin C when very fresh, but NO vitamin C four months after manufacture. It also has little fibre, so it is important to provide hay for your guinea pig.
