Bought this for my three cats. One of them is a piglet and hoovers his food then tries to take the others. Thought by putting treats or biscuits in this it might be a good way to keep them entertained and lower our food costs. They love it, keeps them entertained. Piglet was playing with it for half an hour before realising I'd put wet food down. Loses a star because it slip slides around a lot so I put it on the carpet which wouldn't be ideal for wet food. The bright colour makes sense because dogs and cats don't see colour well so it helps them to see the food.
