Perfect challenge
It took a while for my cat to work this one out. It made me have to consider all the different steps involved and then work out how to get her to understand each step. 1, that the spiky area is a paws not snouts zone, 2, that there's food in the dispensers, 3, that she has to swing them with her paws to get the food. I recommend initially using just one cup and stuffing a tissue in it so the cat can get at the food without having to tip it, it helped show my cat where the food was.
