One of my big female breeders has a color scheme I thought was a little strange when I first got her:


She's all white with black eyes and small black spot at the base of her left ear (another black spot has just recently started coming in at the base of her right ear as well).




Then yesterday in a batch of weaned feeders I received from the same rattery this little guy was in the mix:

Just like my big female he is all white with black eyes and a small black spot at the base of his left ear.

My question: Is this a known rat color morph? I've been looking through catalogs of different rat patterns and so far have not found anything that matches.
