YouTuber Dan Sorkowitz sez of this spectacular Pavlovian role-reversal:
I trained my cat to ring a bell for treats. Now, when he wants treats, he will lay down in front of the bell and ask his servant_me to give him..When he gets full, [keep watching] he will push the bell away, and clean his paws.
