In my opinion, all three have exposure issues (too flat, blown out highlights,...)
#1 The cat's face looks like it was oversharpened to make up for lack of proper focus. Artifacts in the darkest areas:
#2 Blown out highlights and spots that should be cloned out:
#3 Not much is in sharp focus. Specifically, the cat's right eye should be sharp.
Hope that helps,
