Can guinea pigs eat guava, and why?
Guava is very high in vitamin C and a good occasional treat for guinea pigs.
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 guava to guinea pigs
- •How much: A small piece once or twice 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.
