So I got a friend for my guinea pig Henry (the new ones name is Mortimer) and Mortimer is very skittish (obviously) so we are putting the introduction at halt for a few days. I was hoping to do it when cage cleaning day comes up but I don't think I will be able to because he is so scared, he won't eat. He's literally sitting on a pile of lettuce and hay but he won't eat. Every time I look at him he freaks out. You can drop a coin 2 rooms away and he will jump. He doesn't use his hidey either. He just scratches at the wall of the box he's in temporarily. Any tips?
