It take 111 days from pregnancy to birth.
If both parants are hete beige, there is a 25% chance of the kit to be standard grey and it impossible to have a ###### kit.
I'll advise anyone to breed for the better of the genes and not juz breed randomly. If u check ard, there are alot of sub-par chin in singapore that have been abandoned by ex-owners.
