Also suitable for cats (with some limitations)
I bought the tower for my cats. The tower kept them busy until they figured out that you have to pull on the ribbons. Since the toy is actually for dogs, the cones (where you hide treats underneath) are set quite deep. My two can't get them out, so we don't use them. But the tower itself is great. Once the animals get the hang of it, they're very quick to get to the food.
