Can guinea pigs eat cucumber, and why?
Cucumber is a hydrating treat for guinea pigs in small amounts. Watery and low in nutrients, so feed sparingly to avoid loose stools.
Guinea pigs are herbivores who need unlimited hay or grass, a daily portion of fresh leafy veg, and a daily source of vitamin C — which they cannot make themselves. Their gut relies on constant fibre, so too much sugar or any sudden change can cause painful bloat and diarrhoea.
How to feed cucumber to guinea pigs
- •How much: A thin slice a few times a week.
- •How often: An occasional treat, not a daily food. Fruit and sugary veg should be small, occasional treats; vitamin-C-rich veg such as bell pepper make a better daily choice.
- •Young pets: Young guinea pigs have delicate tummies, so introduce any new food gradually and in tiny amounts.
- •Preparation: Always wash fresh produce, remove any pips, stones, seeds, peel or tough skin where relevant, and serve it plain — never with salt, sugar, oil, butter or seasoning.
