"I give these things to my golden hamster Frodo along with wood blocks. He normally takes a while to chew on wood, but he loves these alot. He takes them in his mouth, and carries them around, putting them in various places, like his food dish, where I must remove them, since they are NOT food items. He grinds his teeth healthily on these. They are flavorful, they smell good to me (sweet like sugar), and Frodo actually uses them. Yay!"
