******NEW NEVER USED********* Great for cats and dogs, this fully automatic pet feeder features a tough plastic base that holds a food reservoir for food "on demand." The electronic pet feeder's simple, programmable electronics prompt the feeder to dispense portions from 1/4 to 3 cups at three selected times per day. The unit can be set to meet scheduled feeding times and amounts when caretakers are away, but it is not meant to replace human care--please be sure someone still visits the pet daily. The unit's hopper holds 4.2 pounds of food and accommodates a full range of dry food sizes, shapes, and types. Required batteries, which are not included, sustain a long battery life of six months.
