Give a pigeon a button that when pressed gives sometimes nothin or some food and they go haywire and become addicted to pressing the button.

My dog goes nuts when I’m in one particular part of the kitchen because her treats are in one of the drawers, even though 9/10 times I’m doing something other than getting a treat for her. The payout is often enough that she puts on a show to try and get a treat out of me lol
