These cats are effortlessly fighting over God knows what. The way they are looking at each other seems like there is something serious going on between them but their body movements also depict their lack of energy to fight. See the one on the couch seat, it is trying to make its move but a bit lazy to jump over. He is also waiting for the kitty sitting on the sofa back to make the move first so he can act aggressive and all that but still there is no progress. All they want to do is to meow, purr and wait for something to intervene like food so they can end the fight and go about their businesses.
