Can guinea pigs eat grapes?

Short Answer

Yes

Safety Summary

✔ Safe: Yes — seedless
⚠ Use caution: High sugar; remove seeds
✖ Toxic: No (unlike dogs)

Why

Grapes are not toxic to guinea pigs — unlike dogs and cats where grapes cause kidney failure. They're a safe, popular treat that provides some vitamin C. Seedless grapes are preferred to avoid choking risk from seeds. Cut in half for smaller guinea pigs. High sugar means moderation — a few grapes a couple times a week is plenty.

Portion Guidance

1–2 seedless grapes a few times per week, cut in half.

Risks & Symptoms

Too many: diarrhea, weight gain
Seeds: choking risk
No kidney toxicity (unlike dogs/cats)
