That's interesting, ive often seen them in P@H but never got around to getting them. are you sure its shards and not her peeling of the bark? If it is shards id remove them as hamster pouch things and wouldn't take much to pierce through the cheek or as you mention her throat. Also hamsters grind their teeth together which helps keep them short. Cardboard boxes and tube are good as well as seagrass and wood.

(My rats go nuts over the apple sticks too)
