## Quick answer

Yes. Zucchini is on the RVC safe vegetable list — under its UK name, "Courgette" — the factsheet that puts vegetables, weeds and herbs at 10–15% of the diet as the fresh portion.

The single-source flag applies: only RVC names zucchini directly in our register. That is an A-grade list, but the page leans on the rotation logic the other vegetable sources share — a slice in the daily mix, alongside other greens, rather than a bowl of one vegetable.

## Is zucchini good for guinea pigs?

Zucchini is a mild, watery crunch — low stakes in a fresh-food rotation. Its job is variety: the daily fresh portion is meant to bring different textures and nutrients across the week, and zucchini rotates into that mix without the sugar load of fruit or the high calcium of parsley or kale.

We have no registered vitamin C or mineral figures for zucchini from our sources, so treat it as a rotation vegetable rather than a nutrient anchor. The 10–30 mg of daily vitamin C is safer to cover with the greens our sources name: bell peppers, kale, parsley.

## How to feed zucchini

Wash well, slice raw, and serve at room temperature as part of the daily vegetable rotation. No need to peel — the skin is part of the vegetable as listed — but scrub off any residue.

Introduce it gradually the first week and remove uneaten slices before they dry out. If droppings soften, shrink the piece and let another vegetable take the slot that day.

## Frequently asked questions

**Q: Can guinea pigs eat zucchini?**

Yes. RVC lists it on the safe vegetable list — written as "Courgette", the UK name — with no part or variety exclusions. Raw, washed, and rotated with other vegetables.

**Q: Can guinea pigs eat courgettes?**

Yes — courgette and zucchini are the same vegetable, and the RVC factsheet lists it by the UK name. "Can guinea pigs eat courgettes" and "can guinea pigs eat zucchini" have one answer: a raw slice in the daily rotation.

**Q: Can guinea pigs eat zucchini every day?**

Yes, as part of a varied rotation. RVC places the vegetable list at 10–15% of the diet — zucchini can recur daily so long as the rest of the fresh portion changes across the week.

**Q: How much zucchini can a guinea pig eat?**

A slice or two as part of the daily vegetable portion, alongside at least one other vegetable. The hay rack stays the main event; vegetables are the supplement to it.

## Safety notes

Introduce any new food gradually: a small taste at first, building up over a week or so, and keep every serving fresh and raw. Hay stays the main event at around 80% of the day's eating, with fresh vegetables as the supplement.

**When to contact your vet**: Guinea pigs hide illness well. Contact your vet promptly if your guinea pig stops eating or passes fewer droppings, seems lethargic or in pain, has diarrhea, or shows any sudden change in behavior — small pets go downhill fast, and same-day advice is always the safe call.
