My cat likes to fluff up his tail and backend and whip his tail around when he is angry. Which usually means he just wants to be cuddled. But I can cuddle him because i'm standing up and doing things. He will actively try to get my attention by any means like whacking at me around corners. Or hitting walls or sitting on things I don't want him to sit on or knocking stuff to the floor or chewing on wires or start scratching things I don't want him to scratch. Guy will even meekly meow at me to come pay attention to him. My favorite bit is him clawing at my shirt when he is on the table to make me continue to pet him. I love the shit out of this cat but he is a gremlin and is way too smart for his own good. He will even recognize me in a reflection and just turn around all excited and cuddly just because he is happy to see me. Only for that happiness to turn into anger as I don't pay attention to him.
