This toy nearly killed my cat. The mouse is the perfect size to get lodged in the cats throat, which is exactly what happened when the plastic stick detached from the device (which it did a lot). He nearly choked to death the other night. My suggestion, if you must buy this, use it only under supervision and put it, or at least the mouse away when you are done.
