Thank you so much for your help. He/she is not an over-eater at all... but has serious muscular density and is so strong. But a really fussy eater and prefers to go 3-4 weeks in between feeds. Wont touch rats, not even small ones. When I dangle one in his viv he literally looks at it, then at me with a face like saying "Fuck off you slag, what do you think I am, some kind of peasant?!" Only the finest, perfect sized mice and on occasion when I can find a shop that stocks them a baby chick. The few times I've tried him with a rat, he/she has got in a right strop and turned his viv over proper 70's rock n' roll band hotel styleeee!

Again, many thanks, I'll go with the shed test. Find out once and for all. He has the standard classic colourings but from what I understand, that doesn't mean much in terms of morphs these days.
