Can guinea pigs eat avocado, and why?
Avocado is toxic to guinea pigs. Persin is poisonous and the fat content is far too high.
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.

Persin is poisonous and the fat content is far too high.
