Can guinea pigs eat granola, and why?
Never feed granola to guinea pigs. Far too sugary and processed for a strict herbivore.
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
Far too sugary and processed for a strict herbivore.
