the cresties sit at the bottom of the critter keepers (We have medium ones, they arent too small though) both hallo and trick do it.. traid is usually up in the branches. their critter keeper things are turned upright (Tall) i was just curious as to why they would do that.. i see it during the day and at night. could it be they were just getting a bite to eat since the food thing is at the bottom?
