If you are out at work all day, or your cat likes to graze rather than eat set meals, a gravity feeder keeps dry food and fresh water in reach without topping up bowls through the day. It works just as well for a small dog.

It is a single white unit with two sides. The food hopper holds about 2 litres of dry food and lets it slide down a 45-degree slope into the bowl as your pet eats. The water side takes a 1-litre bottle that refills the drinking bowl as the level drops, with a raised stopper in the water bowl to keep chins drier. Nothing is powered: it all works by gravity. The tank lifts off the base so both parts can be rinsed under the tap.

• Food capacity about 2 litres of dry food
• Water capacity 1 litre
• Works by gravity, no batteries or plug
• Food-grade PP plastic
• About 31 x 25 x 24.3cm
• Tank and base come apart for cleaning

Worth knowing: this is not a timed feeder. It does not portion out meals, so a pet that overeats will simply empty the food side, and it is designed for dry food. Wash it every few days so the water stays fresh.
