If it worked anything like a standard dog treat dispenser, I used a juice bottle and cut holes in it, then stuck dog treats inside for my dogs and it worked beautifully. I imagine any type of juice container (extra points for a large opening) with some holes drilled and somethign like black sunflower seeds inside would be great fun for them.That is crazy! I don't know how impressed mine would be with them. Their favorite past time is digging in the pinestraw or dirt in their yard so tehy can sun themselves. Maybe in winter when they can't dig, then they might like the toys... But I am definitely going to try it! I saw online, someone took a soda bottle- hose weird round ones like the Christmas Coke bottles?- they took one of those and turned it into a roll around treat dispenser. That I think my birds might like and plan to also try one of these days. We don't drink soda, so I am trying to find something else instead since I keep forgetting to buy one of those drinks
