It's easy to train your cat to work the Kitty Food & Treat Machine & it's a lot of fun too! Your cat just presses down on the machine's carpet covered, wheel shaped handle with its paw and out pops a tasty feline treat. Complete instructions are included. The machine and top are enameled in non-toxic red and the pet food tray is made of hi-density polypropylene in black color 13" high fully assembled.
