Cats are cleaver and inquisitive animals. Channel their energy and curiosity into something positive with TRIXIE's Mad Scientist for Cats. Simply place treats inside any of the three beakers and cover with our lids with holes. We've included two sets of lids, each with a different pattern of holes through which your cat must navigate its reward. Once the beakers are correctly flipped and balanced upside down, the treats will fall into the pegs below where your cat will have the added challenge of teasing them out. Mix and match the lids for varying levels of difficulty. We've also included an instructional booklet with tips and tricks to stimulate your cat's sense of curiosity through play. Measures 9 x 7 x 13 inches. Weight 1 lb.
