I have two cats. At first, they are fun and fiesty and love to claw all your furniture. Eventually they chill out with age. And at some point, they turn into raging jerks.
Knocking things off dressers to wake you up, chewing through cords to baby swings, and standing on you with all of their weight are some of the things I experience with my cats.
My favorite (#sarcasm) is when the cat wants it's belly rubbed, so you do, and then it bites you.
