Can guinea pigs eat chard, and why?
Only small amounts of chard occasionally for guinea pigs. High in oxalates and calcium, which can contribute to bladder stones; offer sparingly and rotate.
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.
Warning — what to watch for
High in oxalates and calcium, which can contribute to bladder stones; offer sparingly and rotate.
