Can guinea pigs eat olive oil, and why?
Guinea pigs should not be given olive oil. Added fat is 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.

Added fat is unsuitable for herbivores.
