We got an electric dispenser that lets our cat Tabooger gorge as much as he wants. It keeps giving a slow trickle of food out through the day (instead of 2 or 3 big meals, they get 6 small ones) and we only have to interact with it when the power goes out or it needs another bag of food in the hopper.

The reliability of food showing up, even when we were gone, that may have been a big contributer to our orange getting over his eating disorder.
