Gravity Pet Feeder and Water Dispenser with Clear Canister

This feeder works with gravity alone, so there are no cords, batteries or timers to set up. A clear plastic canister with a white lid sits on a sloped base. Fill the canister with dry food and the tray in front of it fills as your pet eats, so the bowl stays stocked between top-ups. A matching water version uses the same canister-and-base shape to keep a drinking dish topped up the same way.

Choose either the food feeder or the water dispenser in blue, pink, green or gray. The two designs share the same footprint, which makes a tidy pair on the floor or along a wall. Each unit measures 14.0 x 6.7 x 10.6 in (35.5 x 17 x 27 cm) and weighs about 1.8 lb (800 g) empty, and it is made of plastic.

The tray is a wide, low oval, so it works for cats and dogs that like to eat from an open dish. A clear canister lets you see at a glance when it is time to refill. Because the food drops into the tray freely, it will not control portions, so it suits pets that eat when they are hungry rather than ones that need measured meals. Set it on a flat spot, and wash the tray and canister regularly.
