Can guinea pigs eat yoghurt, and why?
Yoghurt is not suitable for guinea pigs. Herbivores cannot digest dairy and so-called yoghurt drops can be harmful.
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.
