Just wondering? You know when the popcorning verges on violent lol Mine popcorn like crazy when I'm scooping their poops, I think they like the sound of the bag I use. Tigger popcorned into my knuckle yesterday and I felt that so it must of hurt him, and they tend to whack quite hard into the sides of the cage! Do I need to get the piggies a padded cage for their own protection lol
