Yes guinea pigs do eat pumpkin seeds. But I would buy it in the food not from a pumpkin
Do Guinea Pigs Eat Pumpkin Seeds?
No because when they eat them they get it stuck in there teeth it could harm them
I think they might if given the opportunity but I'm not sure if it's good or bad or neither for them. I would be sure of that first. Here's some excellent cavy sites for you to bookmark that might have that somewhere in one of them. :-)
