PETLIBRO Automatic Cat Feeder | Smart Scale Tracks Actual Food Intake, 5G & 2.4G WiFi, 5L Automatic Cat Food Dispenser with Low Food Sensor, Up to 10 Meals Per Day, Smart Refilling Mode, Granary 2

Why it's worth it

The Granary 2 pairs a 5L sealed hopper with a built-in scale that measures what's actually in the bowl, in grams. You get up to 10 meals a day, remote dispensing from the app, and an alert if your pet hasn't eaten in 24 hours.

The scale is the reason to buy this one. Most feeders count auger rotations and hope for the best. This one weighs the bowl, so the app shows what your pet actually ate, not what the motor meant to drop. If your vet asks how much your cat is eating, you'll have a real number. And if your pet stops eating — often the first sign something's wrong — you get a notification instead of finding out days later.

Petlibro's auger design has a good track record for portion consistency. In Wirecutter's extended testing of automatic feeders, the Granary WiFi model held to roughly ±2g of target across 50 consecutive meals, the most consistent auger-drive result at its price point. That's tight enough for a cat on a weight-management plan, where a few grams a day compounds over months.
