I have 4 rats as pets princess which look just like the last picture the cream and white and oreo the black head with white body cassie white with black dolmation spots and butter that looks just like princess. When your breeding be carefull after you know they had their breeding session remove the male. and do NOT touch the babies momma will end up eating them. I would love the solid brown as a pet but cant find one. You got very pretty ratties good luck with breeding. They will have alot at one time and if you leave the male in you will have around 20-30 babies between litters. HAVE FUN!!!
