We have had this robo-cat-feeder for a year now. As you can see in the video, Trigger hovers nearby when it's feeding time.
He swipes at our legs as we walk past to let us know we should manually depense more niblets.
If he's not nearby, when the niblets hit the metal bowl (which you can hear in the video), he comes running from wherever he is in the house!
It's a Pavlov's Cat device! 🐈
