On the table: With these automatic feeders, you can feed and water your animals throughout the day. Don’t worry: it won’t miss anything even if you’re not around! Simple: no batteries or USB power needed! Place the bowl on the ground for easy access by your cat or dog and fill it with the required amount of water/kibble. Stability: Both tanks have non-slip bases to ensure stability. You don’t have to worry about your dog or cat accidentally knocking them over while eating. Care: We recommend manually cleaning both tanks approximately every five days.
