The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other dog and cat food, health, gear and grooming we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
This is a 2-in-1 station that keeps food and water on opposite ends of the same anti-tip base. The dry food side is electric with portion control and precision feeding, while the water side works purely by gravity from a 3.5 liter reservoir and needs no power at all. The design is built specifically to prevent cross-contamination between the two sides.
Total combined capacity across both sides runs to 36 cups (8.5 liters), and the stainless steel bowls are dishwasher safe for easier cleanup. A desiccant bag is included to help keep dry kibble fresh, and the unit is backed by a 2 year manufacturer warranty.
It runs on corded electric power through a USB-C adapter and weighs about 3 kilograms. The footprint is long and narrow at 22.6 by 6.46 by 13 inches, so it needs a stretch of wall or floor space rather than a compact corner.
