Push-Button Kitty is a 1952 Tom and Jerry cartoon.
Mammy Two Shoes is sweeping the floor and Tom relaxing near Jerry's mouse hole, not caring or not noticing as Jerry comes out then returns with a piece of cheese. Mammy then receives a package she has been expecting. She opens it to reveal Mechano, a talented robotic cat, just the opportunity to downsize Tom after his laziness. In disbelief, both Tom and Jerry laugh out loud. Mammy then turns on Mechano with the remote control, and it immediately darts to the mouse, hits him with a hammer, and slingshots him out through the window.
