The Cooper Pooper is the first fully indoor willow feeder built at Wheaton Labs. Unlike outdoor or skiddable systems, this one is integrated directly into Cooper Cabin. It keeps human poop out of rivers and groundwater while offering the comfort of an indoor bathroom. Solids are stored in a tall sealed can, liquids are diverted to a greywater line, and a solar-powered fan ensures odor-free use.
