Yes, guinea pigs can eat pumpkin. Give a few small cubes of raw pumpkin flesh per guinea pig, a few times a week, as part of their daily veg. The Vet Desk calls it safe in moderation. Take out the seeds, cut off the tough skin, and never feed cooked, tinned or spiced pumpkin. Pumpkin is low in sugar but also low in vitamin C.
| Safe? | Yes, raw flesh only |
| How much | 2 or 3 cubes, each about 2 cm (3/4 in), per guinea pig |
| How often | A few times a week, with gaps between |
| Best served | Raw, peeled, seeds out, in small cubes |
| Watch out for | Seeds, soft droppings, gas |
Is pumpkin good for guinea pigs?
Yes, it is a useful change in the veg bowl. Worked out from the Guinea Lynx food chart, raw pumpkin has only about 1.4 g of sugar per 100 g (3.5 oz), far less than fruit, and it is rich in vitamin A. Burgess lists squash, the family pumpkin belongs to, among its safe foods for guinea pigs.
It is not a vitamin C food, though. Pumpkin has about 9 mg per 100 g, and the Vet Desk notes it is not a significant source. VCA says guinea pigs need 10 to 50 mg a day, so keep peppers and leafy greens in the bowl alongside it. Our vitamin C guide lists the best sources.
How much pumpkin can a guinea pig eat?
Start with one or two small cubes, then build up to two or three cubes, each about 2 cm (3/4 in), per guinea pig. The Vet Desk suggests feeding it a few times a week at most, with a few days between, because its water content can cause loose droppings or gas if fed too often. Count it as part of the cup of veg the PDSA recommends each day, not on top of it. Our guinea pig diet guide shows how that cup fits around unlimited hay.
How to prepare pumpkin
- Use fresh pumpkin. Firm, clean flesh only. Nothing soft, slimy or past its best.
- Wash and peel. The Vet Desk does not recommend the tough rind, so cut it off.
- Scoop out every seed. Remove the seeds and the stringy pulp around them.
- Cut small cubes and serve raw. Mix them in with the day's greens. Keep the rest wrapped in the fridge for a day or two.
Grating a little raw pumpkin over the leafy greens is a good way to tempt a guinea pig that won't try a new food in cube form.
Which parts and forms are a no?
- Seeds: no. Choking risk and high in fat.
- Skin: no. Too tough.
- Leaves, stems and vines: one leaf at most, rarely. High in calcium.
- Cooked, roasted or tinned pumpkin: no.
- Pumpkin pie filling, soup or anything spiced or sweetened: no.
- A carved pumpkin that has sat out: no. Treat it as spoiled.
Who should skip pumpkin?
Go gently with babies and guinea pigs with loose droppings or a sensitive stomach, and introduce it one new food at a time. Guinea pigs with a history of bladder stones should have the flesh only, never the leaves.
What to offer instead
Close cousins work well: courgette (zucchini) is another squash for the veg bowl. Carrots and sweet potato are other orange veg people ask about, though both are sweeter. See what guinea pigs can eat and our guinea pig care guide.
Pumpkin questions
Can guinea pigs eat pumpkin seeds?
No. The Vet Desk, a vet-reviewed guide, says to remove pumpkin seeds because they can get caught in the teeth or throat and are very high in fat. VCA also advises against feeding seeds and nuts to guinea pigs because they are too high in fat and carbohydrates. Scoop them all out.
Can guinea pigs eat tinned or cooked pumpkin?
No. Guinea pigs do best on raw plant food, and the Vet Desk says they can't handle cooked or flavoured foods. Tinned pumpkin is cooked, and pumpkin pie filling is sweetened and spiced. Stick to a few cubes of fresh, raw flesh instead.
Can guinea pigs eat our Halloween pumpkin?
Only if it is freshly cut and clean. Our sources don't cover carved pumpkins, so we reason from the basics: a pumpkin that has sat out with a candle inside, gone soft or started to grow damp patches is spoiled. Use fresh offcuts from carving day and put the rest in the compost.
Can guinea pigs eat pumpkin leaves?
Only a little. The Vet Desk says pumpkin leaves, stems and vines are high in calcium and should be offered rarely, with one leaf being more than enough. If your guinea pig has had bladder stones, skip the leaves altogether and give the flesh only.
