My guinea pigs are 2.5 months old. This morning they all of a sudden stopped eating hay. They had lettuce and pellets. But now, they're not eating hay or any other vegetables I kept for them. They're not even letting me touch them as if they're scared of me. They ran around a bit but are very silent now except for the occasional fighting. I'm scared. Please help me. If something happens to them I'll literally die. Please help. I don't have any exotic vets in my area. They don't deserve to suffer.
