Thank you for posting this because my kitty was just doing the SAME EXACT THING... looking out the window at birds or God knows what! It's too cute!!! I was trying to get him on video, but by the time I got my phone going, he buggered off.
IF I didn't have a cat video with exactly the same cat stuttering, I'd say this was fake ;) But I definitely vote LIKE, because it's awesome!! (The video quality is making it look weird though)
