My Greencheek has no lower mandible. She has a tiny bit of lower beak growth in one corner. Shredding anything harder than paper towels has been difficult until I gave her a munch ball. It's taken her days but she's been going at it bit by bit and having a (munch) ball playing on the bottom of her cage. So happy to have found something that she can play with. When I asked her if she liked her new toy she replied "thank you, good girl' So I guess she was happy with my purchase.

My green-cheeked conure didn't pay too much attention to these at first, but then I noticed they were woven loosely enough for me to insert an unshelled, unsalted pistachio nut, one of his favorite treats. When I do that, Popeye plays with it for ages, working it this way and that, because the nut must. come. OUT! When he's worked it enough, the gaps get large enough that the pistachio can slip right out, so and I do the same thing with a larger Nutri-berry, which means the toy is appealing for that much longer. He'll chew at this thing until there's nothing left but a few scraps of vine!

My budgies love these small munch balls. They chew through them pretty quickly, so it is wise to keep several on hand! :)
