yea actually i think i had one rat that had it a while back, i fed it off. i hear alot of different things about megacolon and some say high whites, some say it has to have a certian blaze.... what i do know is i have about 20 breeder females that all have litters right now and are doing fine. i have tried to find more info on it but there is not much out there that i could find.... reminds me of the caramel albino and its "kinking"
