I have a cat that uses buttons to talk - it's not bullshit. It asks for food, for clean litterbox, to play. It understands the concept of "now" and "later". It argues with me when I tell it "no". It uses the buttons when I'm not looking at it.

Took a shitton of training, but now it gets excited for new buttons and tries them out and to see what I do in response to it.
