The Catit Senses 2.0 Digger encourages cats to work for their food or treats in a fun and natural manner. Its smart design plays on your cats instincts to paw out smaller portions of food, which stimulates activity and reduces binge eating. Insert kibble or treats into the various tubes for your cat to smell and paw out! The tubes have rounded ends, making them easy to use and clean. There are 3 short narrow tubes and 2 long wide tubes so you can change between difficulty levels. The sloped surface can be used to add extra kibble in the front. The digger is an excellent dish for when you’re not at home. The cat will first eat the kibble that is easiest to access, after that it has to ‘work’ a little harder for its food. The Digger is easy to disassemble and clean. We recommend hand-washing each part with natural soap, free of chemicals or abrasive solutions and rinsing thoroughly.
