I watched the video and I want to believe, but... I don't know. I have cats, I know cats are intelligent, cats can be trained to understand single words, etc. But I'm just not convinced any cat can string together English sentences like this. Also, the concept of time might be a bit abstract for a cat who is always living in the present moment. And then there's the most viewed video on that channel[1] where he presses the "cuddle" button, and then... doesn't cuddle. He seems like he knows pressing a button get a reaction, but he doesn't know which button is which. Good morning human, time to play with the disembodied voice buttons again.
Like I said though, I want to believe. Can you think of any longer videos that might convince a skeptic?
