Neat capture! I do a lot of slow-shutter speed photography, especially in the summer-night beach volleyball is a perfect subject for that. Judged by the lighting and depth of field and camera motion, it looks like your aperture was pretty wide, and your shutter speed was probably a bit below 1/10 of a second (most people get camera "wobbles" below 1/15th of a second. If it was taken with a point-and-shoot camera, my guess is that it metered for the dark patches on either the cat or the ground-definitely in "spot-metering" mode.
I just realized as I typed that paragraph that it's official: I am a complete and utter photography nutbag. Here's one I took of myself on long shutter speed. It was one of those evenings when boredom overtook me, so I tied rags to my feet and polished the 2nd story of my house, which is all wood flooring. Also, I'll throw on one of the beach volleyball shots I took-you can see the similar effects as your cat photo, except I used a tripod, so there isn't any camera shake (or very little).
