I think it's time for a challenge. Let's take this to a higher level.
Cat #1: Oh she is definitely introverted. She likes to sleep 24 hours a day. She isn't very vocal. She loves to go outside. She loves to be pet but only a certain way and if you don't do it right she'll swat at you or pretend to bite you but only if you press further will the claws come out. She can tell when I am upset and tries to comfort me. She follows a routine. She is very selective with strangers. Some she will come up to and some she will hide from.
Cat #2: She will not shut up. She meows 24 hours a day and constantly wants to be played with. She's not a kitten anymore but she still acts like one. She likes to talk. When strangers come over she will hide and never come out. She always acts like there isn't enough food and overstuffs herself. She is extremely affectionate.
