A Sphynx cat picture is rather hard to get hold of as this breed is rare. However, I've just been to the National Cat Club Show 2007 in London and got one or two pictures. Also, Helmi Flick has photographed on or two Sphynxs in her time and (yes there are more), one of the Flickr photographers has taken some great pictures of Sphynxs.
Perhaps the best thing to do is to provide some links to places on the net where you can see the very best Sphynx cat pictures (actually photographs) both amateur and professional.
Here are the links:
On this blogger go here
On the internet go here
On the internet try this
