Typically the "snow" line I believe is associated with corn snakes, and this is a combination of hypomelanistic (no black) and anerythristic (no red/orange). these are two different types of "albinos" (i put in quotes because neither is a ture albino, just lacking one type of pigment). since yellow rats dont' have significant amounts of red or black, it's hard to get a snow yellow rat. i have seen white sided yellow rats, however.
