My Macaw loves the Treasure Chest and love taking out these pieces and chewing them. One of her faves!
Haven't used them yet but intend to as needed. We have the treasure chest for our grey and she loves it plus it doesn't make a lot if mess. She's chewed on a few pieces but then when she drops them, I put back in chest. She can be challenged with the chest for an evening. I would buy another if this one doesn't last altho it's well made.
