Which vegetables can guinea pigs eat every day?

Short answer: about one cup of washed, drained vegetables per adult per day, rotating low-calcium, vitamin C-rich options.

1. Daily rotation — red/yellow bell pepper, romaine, cucumber, coriander, celery leaves, green leaf lettuce.

2. A few times a week — tomato (no leaves or stalk), courgette, carrot (small amounts, sugary).

3. Introduce one at a time — watch appetite and droppings for 24 hours.

4. Preparation — wash, drain, serve at room temperature and remove leftovers within 2–3 hours.

5. Hay stays the staple — over 80% of the diet; vegetables are daily nutritional support.
