6 non-removable wing nuts, no digging around the bottom of the cage to find when your Bird gets to its treat
Cage-side mount or hang
Birds love the Busy Barrel's bright colors and the clanking sounds it makes as they take it apart by unscrewing the wingnuts. Pat a treat inside the box and let them go to town! The wing nuts don't fall off, so you'll never dig on the bottom of the cage to find them.
