A 12 hour one with stops every four hours. Reset the timer when you fill the feeder in the morning.

If this was an interview question I would reject the job. You don't seem worth working with.

That’s not going to work if you’re going on a vacation for a week. You want to fill the feeder with a week’s worth of food at a time and have it feed every day according to the schedule. Control the power to the feeder with a smart plug and set the feeder’s internal timer to 4 hours.
