I'm also wondering if anyone who has changed the pellets has their cage on a second level of the house? And if you have a loft do you put them up there or do you still use flippers or fleece and pads/towels? I currently use fleece flippers in our 2x4 cage and in the loft I have a large litter box with care fresh and the other half of the loft has just a fleece flipper. I am sick of the piggies getting scared and getting litter all over my son's floor. I am wondering if I should at least try to use just the pellets in the litter box/kitchen area and if that would help. I think my hesitations for the pellets is the noise that people mention since it is in my son's room and hauling those pellets down stairs and outside. I would love to hear more information about hauling the pellets outside. Thanks!
