Quick answers: what can guinea pigs eat?

Safe to feed every day

Timothy hay and other grass hays, romaine and leaf lettuces, bell peppers, cucumber, zucchini, celery, cilantro, basil, dill, mint, dandelion greens and fresh grass.

Feed sometimes, in small amounts

Spinach, kale, parsley and Swiss chard (high in calcium), carrots, broccoli, cauliflower and cabbage (can cause gas or are sugary), tomatoes, and fruit such as apples, strawberries, blueberries, grapes, oranges, bananas and melon.

Never feed

Avocado, onions, garlic, leeks, chives, chocolate, mushrooms, raw potato, rhubarb, iceberg lettuce, nuts, seeds, dairy, meat, bread, sweets and fruit pits.

Tips for feeding guinea pigs safely

  • Give vitamin C every day. Guinea pigs cannot make their own. Red, yellow and orange bell peppers are a great source.
  • Introduce new foods slowly. Offer one new food at a time in a small amount and watch for loose stools.
  • Wash everything. Rinse fresh produce, and never feed plants that may have been sprayed with pesticides.
  • Mind the calcium. Foods high in calcium and oxalates, such as spinach and kale, are best a few times a week.
  • Keep fruit as a treat. It is high in sugar, so offer only a small piece once or twice a week.
  • Remove leftovers. Take out fresh food that is not eaten after a few hours.

If your guinea pig eats something on the Never list, or stops eating, contact an exotic animal vet right away.
