Our current cats:
Moxie: INFP (but he's extremely timid, so he doesn't represent well)
Peaches: ISTJ (she's my honey!)
Mr. Smooch: ISFJ
SassyCat: ENFJ (guess who lies in ambush at the back door?)
My all time favorite kitty was our old grey tabby, Daisy, who tolerated being called a girl's name to make us happy. He was also ISTJ. Curmudgeonly but very cuddly. I used to find him asleep in the laripe shrubs and since the sun had made him melty and sleepy, I'd pick him up and cuddle him and he couldn't fight back!
