Cat Dog Automatic Feeder and Water Dispenser Set: one gravity food feeder and one gravity water dispenser, ideal for small to medium cats and dogs. The waterer is molded from Bpa-free, food-grade plastic. The feeder base features a removable stainless-steel bowl that keeps kibble fresh, resists rust and deformation, and pops out for quick hand washing. Together the units store roughly six pounds of dry food and one gallon of water, supplying an average cat or small dog for seven to nine days, or a larger pet for three to five days. Gravity automatically replenishes the bowls as soon as food or water levels drop, so your pets stay fed and hydrated while you work, travel, or host guests. A transparent reservoir lets you monitor levels at a glance, and the water dispenser s spring-loaded, spiral valve prevents drips and leaks. For longest life, wash by hand if you use a dishwasher, disable the heated-dry cycle.
