Gravity Pet Feeder or Water Dispenser, 1 gal (3.8 L) Capacity

This is a gravity-fed station for cats and dogs. A clear 3.8 L (about 1 gal) bottle sits on a low plastic base, and as your pet eats or drinks from the tray, more food or water slides down to refill it. You choose between two versions: a food feeder for dry kibble, and a water dispenser for drinking water.

The whole unit is 14 in wide, 6.7 in deep and 10.6 in tall (35.5 x 17 x 27 cm), a compact size that fits against a wall or in a corner of the kitchen. It is made of plastic and comes in blue, pink, green and gray, each with a pale base.

To set it up, fill the bottle, close the lid and seat the bottle onto the base. A gravity feeder holds a supply for several meals, so it is handy for days when you are out of the house for a few hours. It is not a timed or portion-controlled feeder, and a pet that eats quickly can empty the tray fast, so it suits steady grazers best.

Because the tray is shallow and low, check that your pet can reach it comfortably. The unit has no power, so there are no cords or batteries to worry about.

Wash the bottle and tray with warm water and mild soap on a regular basis, and rinse well before refilling.
