My cat, Carl loves to go outside just as much as I do, but he is not allowed as he is a house cat. I had just walked out my front door to watch a storm roll in and Carl ran up behind me, put his paws up on the glass door and begged me to let him out. I took the opportunity to try to capture his expression of desire - he wanted nothing more than to be on the other side of that glass door and you can see it in his eyes.
