Thanks everyone, I do agree Nova is a little stunner (but then I'm biased!).
Yep, Nova's coat is changing fuzzies are slowly but surely giving way to a silk like pelt and her markings are great due to the good contrast her coat has. I expect it will get even better over next couple of months.
She is facially different from the boys, some of that will be bloodline but to be honest, the girls are much more delicate facially than the boys anyway which does give them a bit of a different look.
I sent Nova's pics to Pauline her breeder and she is going to put the third pic on her special kitten page on her web-site. I'm delighted by this as its typically her foundation cats that are on that page but Nova is an excellent example of the bengal breed (even if I say so myself!).
She also has the most fantastic personality, very loving, always wanting plenty of kisses and cuddles which I'm more than happy to supply
