Nothing new to people using buttons to train their pets. Plenty of them learn words and start forming sentences. Some have over 50 buttons that the pet knows. They show empathy, they get sassy, they argue with you. Animals aren’t as stupid as people think, as long as they have constant stimulation / training. Leaving a cat indoors for 8 hours for work each day won’t let you train with them enough for it to reach any sensible effects.
