Like any of us, animals decide who they like and don't like as much. My Dad did not like cats, but when his little princess (no, not me...my Sister) wanted a cat, he let her pick a cat from the shelter. Who did the cat repeatedly sit on? Yep...in the end I think he really loved that cat, but he'd never have admitted it.
I seem to make animal friends easily, but for some reason Parrots in particular are drawn to me in an almost freakish way.
