Honestly, if you have the money, just get a Superfeeder. I have 2 of them for my cats and I love them.

Basically, they’re like an enterprise version of a consumer grade cat feeder. Completely no nonsense, all physical adjustments, and super customizable. I have them hooked up to my home assistant install to be able to better control when the cats get fed (because the little piggies would over eat if I let them) and ensure the automations run as expected (which is great for those with pet anxiety). I’ve had mine for 4 years (and 2 sets of kitties) now, and it’s a breeze to change settings when you have to change foods, if a bit fiddly to dial in how much you’re giving them.
