safe plants to eat

Question
Are all grasses and weeds safe for guinea pigs to eat? What should I NOT feed him from my yard?

Answer
Hello,
Not all grasses and weeds are safe for guineas to eat.
If you go to this website it gives you a list of what plants/weeds are  safe for your guinea to eat, what isn't safe and what people are unsure about.
I hope this helps
