Safety Summary

✔ Safe: Yes — very small amounts
⚠ Use caution: Very high sugar
✖ Toxic: No

Why

Bananas are safe for guinea pigs but very high in sugar — one of the highest sugar fruits you can offer. Small amounts occasionally are fine, but banana should be a rare treat. Guinea pigs need daily vitamin C and should focus on bell peppers, leafy greens, and other lower-sugar foods as their main produce. Some guinea pigs love banana, some ignore it.

A thumbnail-sized piece once a week at most.
