Ive had my one piggy for a year and just got him a brother so he isnt lonely. I had them in separate cages for a week and introduced them everyday, then put them in a cage together. But now my piggies are incredibly loud at night! They dont fight but make noises (sqeaking and rumbling) to each other. I cant sleep at all. I put food in there cage and tried to separate them and they are still loud. What do i do ?
