Great Idea! Everyone knows that cats love cardboard boxes. This combined with a Spardosen function gives a great gimmick! As a cat fan Must Have! Just funny the coin store and watch the little Kitty at pilfer ^^ Works great and is well made! Only the speaker is a bit noisy, but with adhesive tape can reduce the volume by sticking a small strip through the opening. The engine itself is not very loud. The Kitty can steal all the coins, from 1 cent to 2 Da makes saving fun! ^^ Also great as a gift! Unfortunately, no choice what "cats cardboard" you get. Is well 3 types of boxes, where quite possible the cat itself has a different color, if one starts from the front of the packaging. But all look iwi from great ^^
