Anton_ if you haven't got it, a good starting place is the excellent little Dorling Kindersley handbook on Cats by David Alderton_ its got pics of about every possible cat you are ever likely to see_ plus a few that I'm sure you'd have to travel to Mars to see! (try the Sphynx on p178!) There's a good section at the beginning on face shapes etc. Anyways if you're gonna have a go I'm going to give up on my project to remodel and remap the P4 kitty_ a new millenium cat would be far more preferable! Good luck!
