ROTATING TIER DESIGN FOR PROLONGED EATING TIME: The bowl has two stacked layers that spin when your pet pushes them. Food moves from the upper section to the lower compartments as the disc turns. This means your dog or cat must work for each mouthful rather than gulping everything at once. A design that turns a one minute meal into a five minute activity. TREAT RELEASE GAPS FOR MENTAL STIMULATION: Small bone shaped openings let kibble fall through as your pet rotates the top disc. The holes are sized to release a few pieces at a time rather than letting all the food spill out. Your pet has to figure out how to turn the disc to get more food. A puzzle feature for dogs who finish their meals too quickly and need brain work to slow them down. TWO LAYERS FOR DOUBLE THE CHALLENGE: The upper tier holds the main portion of kibble while the lower tier stores a smaller amount. Your pet must empty the top before reaching the bottom layer. This creates a longer feeding session than single level slow feeders. A multi stage design for dogs who have learned to defeat simple puzzle bowls. NON SLIP BASE FOR STABLE PUSHING: The bottom of the bowl has a rubber ring that grips smooth floors. This stops the whole unit from sliding across the kitchen when your pet paws at the rotating disc. The bowl stays in place so all the effort goes into turning the top rather than chasing the bowl. A stability feature for enthusiastic eaters who push their bowls around. EASY TO DISASSEMBLE FOR WASHING: The two tiers separate so you can clean every surface where kibble dust and saliva collect. The smooth plastic does not trap food residue in corners. You can wash the parts by hand or put them on the top rack of a dishwasher. A maintenance design for owners who feed wet food that leaves sticky residue.
