Can guinea pigs eat watermelon?

Short Answer

Yes

Safety Summary

✔ Safe: Yes — seedless flesh and rind
⚠ Use caution: High sugar and water content
✖ Toxic: No

Why

Watermelon is safe for guinea pigs and a refreshing summer treat. It provides vitamin C (which guinea pigs require from food) plus hydration. The rind is also safe and lower in sugar. Remove seeds to prevent choking. The high water and sugar content means it should be an occasional treat rather than a daily food.

Portion Guidance

A small triangle of watermelon a few times per week. Rind and seedless flesh only.

Risks & Symptoms

Too much: loose stools from high water content
Sugar: weight gain, digestive imbalance
No toxicity
