Interesting question. I probably would not be interested in photos of cats other than the ones I own. But, my aunt probably would be. (And she would probably purchase such a picture to give to me as a present.

)
When I looked at the picture you attached, the first thing that came to my mind was a greeting card. You know the ones with the cute B&W images of animals doing silly things or with cute/silly expressions. I think that's the "wow" factor that Roger mentioned.
In this particular photo, the white fuzz distracts me from really seeing the cat. Having not seen your other photos, I can't comment on them, but I would bet you've probably got some good ones. If I were you, I'd pursue the greeting card route and see what opportunities exist in that market. I haven't done that myself, so don't know if it's any easier than selling your own prints. (It's possible you could make/distribute your own greeting cards to local stores. I know there are people in my local area that do that - I don't know how widely they distribute their cards though - or how profitable it is.)
Another thing you might want to try is selling a few of your prints on eBay and see if there is a response there. It might give you a feeling for whether or not there is a market. Check out

Good luck!!
