Can guinea pigs eat black pepper, and why?
Guinea pigs should not be given black pepper. Spices are unsuitable for herbivores.
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.

Spices are unsuitable for herbivores.
