DIY Hamster Ball Wheel

Convert a hamster ball into a hamster wheel! Drill a hole through the center of the hamster ball lid and through the base of the ball. Cut out three large triangles from the lid for your hamster to use as a doorway. Thread a metal rod through the holes in the lid and base of the ball, drill holes on either side of your hamster’s cage to accommodate the metal rod, and glue or thread a nut onto either end of the rod to hold it in place.
