First let me say that I like any photo that's of a cat. I like the first shot the best because to me it has feeling to it - the cat appears to be in deep thought [probably about his dinner lol] With the last one it would have been better if you had gotten the right side of his face. With the second shot the sky is blown out and the rocks are too dark.
The third photo here has something ... the first two are not so interesting, the photo of the rocks does not mean anything to me. Composition divides the frame into two equal halves, photographing into the sun makes the dark rocks all black and featureless ... consider that one to be a failed attempt, I should say.
I really liked all 3, but I took the liberty to photoshop the rock scene real quick. Didn't spend much time on it, but I took out the flare and changed the exposure. It added a little bit of noise but see what you think:
