A simple (gravity-powered) cat feeder works perfectly well. Unlike dogs, cats are smart enough to eat only what they need. I have to refill the feeder for our 3 cats maybe once or twice a month.

As the person who made this project, I assure you this isn't true.

I have one cat who is a reasonable free-feeder, and another cat who is a food beast and will devour everything in his grasp.

Could you tell my immense cat about that?

Hah, not all cats! Ours will eat everything that is put in front of it, and then throw up

Not all dogs are fatties. Mine only eats what he needs.
