Hey, I'm a new guinea pig owner and I just got them today. I was expecting them to be very shy and to my surprise they both started exploring almost instantly! Except now it's been a few hours and both are huddled in the corner under the second shelf of the cage. xP I thought this might be normal and it's probably fine but they won't eat a thing! They drank some water earlier and nibbled on some hay but they won't touch the pellets or chew sticks and now won't go anywhere near the hay. They aren't making any noise and they aren't eating or drinking. I even tried coaxing them out with a carrot but they didn't budge. I'm kind of worried. D: Are they just scared of their new home or tired or something? Or is something wrong?
