Can Guinea Pigs eat ...?
Food safety index

Peas are a safe, nutritious treat for guinea pigs when offered in appropriate amounts. They provide useful vitamins — including vitamin C, which guinea pigs cannot synthesize on their own — along with plant-based protein and fiber. Overfeeding should be avoided due to the natural sugar and starch content, but moderate servings pose no meaningful health risk.

Asparagus is safe for guinea pigs in moderate amounts and provides useful nutrients including vitamin C, which guinea pigs cannot synthesize on their own. There are no toxic compounds in asparagus that pose a clinical risk to this species. Like any vegetable, overfeeding can cause digestive upset, so portion size matters.

Bell peppers are an excellent food for guinea pigs. They are packed with vitamin C, which guinea pigs cannot make themselves, and are low in sugar, oxalate and calcium.

Cucumber is a safe, hydrating vegetable for guinea pigs and can be offered regularly as part of a varied diet. It contains no compounds toxic to cavies, and most guinea pigs find it highly palatable. Overfeeding can cause loose stools due to the high water content, so moderate portion sizes are key.
