What is this cat doing?
Taking a common sense viewpoint it looks like the cat is checking whether the cat that he sees in the mirror is him. He waves his forelegs around to see if they move in the mirror. That’s what it looks like but no doubt he is doing something else.
The video begs the question whether he realises it is him in the mirror. Experts say cats are not self-conscious.
The video paid of the video maker’s tuition fees so it did pretty well.
