Thanks Mr VERITAS. No wasnt any of those, but whilst looking at them i did spot a picture of a Siberian. Its not a total match as this cat has a shorter smoother coat than a pure siberian would have, but its pretty close. Right eyes, right markings on head and tail, same head an body shape and good colour match.

Imagine this one as a grown up, with shorter fur, and we're there!
So Schutz, i think he is probably a cross between something! But at least i know what kind of cats to look for to find something similar, once i'm allowed another cat by my OH!!!
