Though it took a few tries to for my mini lop to understand it, she tried pawing it first, and with no avail, but very cute to watch, she soon realised that she has to header it, though this toy is best used out side the cage, with lots of room, as she has nudge it around for a while to get the treats out, and make sure you buy the right size treats to come out so they can fall out easliy, i am very happy to own this item and she even likes to roll it around when there is nothing in it, though she does get confused :P i recomend
