Yep you need to pull the hid, I'm breeding a Siamese Blue Tortie with a Solid Bengal Black and in 4 breeds have only had Siamese Blue Tortie back, popped baby refusing to pass his hid so far though, but its a strong indication that it might be dominant to Bengal Black meaning your Snowshoe Cream may hide Bengal Blue.
Looking at the Bengal Black I am using I can't see anything else in his pedigree but thats no guarantee which is why I have popped baby #1 to pull his hid, I think I posted him further back in this thread
He breeds again tomorrow so with luck he will play nice this week!
