Plastic Bottle Hut & Rat Pool
Upcycle a milk jug into a hut and pool for your pet rats! Cut off the bottom of the milk jug and cut a doorway hole from the side of the jug. Use scissors to re-cut the edges to be smooth or cover the edges with duct tape. Paint or decorate the hut, fill the pool with water and consider adding veggies to the pool as dive toys.
