Cats have the ability to suddenly materialise onto any unoccupied chair that is within a 60 foot radius. They sense leftover body heat and so tend to gravitate over to chairs people have already sat on, teleporting there with a dragon ballZ sound effect and absorbing the chairs heat. Once all the heat is obtained, the cat seeks out another chair until it can gather enough energy to go supernova, which it is never able to do because people will push cats off the chairs. But one day the catastrophe will commence and all humans will be the ones who have to scratch posts and eat from bowls. One day our cat overlords will destroy us all. Then you will all realise that you spent way too long reading this message about cats stealing chairs and that I wasted like two minutes of your time with whatever this rambling comment is. Have fun during the end of human kind when cats take over.

This is how cats work.
