The Catmate C50 is designed to feed your cat or small dog up to 5 meals. The first compartment is open to serve your pet's initial meal immediately, and food is kept fresh in the 4 remaining easy-clean compartments, revealed by a rotating lid. Just set the battery-operated timer to the required mealtimes, up to 96 hours later. Perfect if you are going away or if you have a feral cat in your neighborhood. Batteries and ice packs not included.
