So if we Dan eat it, can Guinea pigs eat olive oil?
It is definitely worth steering well clear of it as a food for your guinea pigs.
If they do happen to take in some olive oil for some reason, then it really depends on how much they take in as to the action you take. If its only a very small amount, they should be fine. But if its any more than that, then do seek veterinary advice.
