Black eyed white is the most recent discovery. I first saw this variety being sold by a breeder in Holland in late 2017 but it has been found in pet shops in the North of England from 2018 onwards.
White first came to my hamstery in January 2020 and little is known about this variety at all so far. We don’t yet know if it’s dominant or recessive or what gene or combination of genes causes this appearance.
Hopefully, with further breeding, more will become clear.
