Just a teenie little question

[Mary McDermott]

You know how most blacks have just a little white on them (fingers and the
mouth/throught), well I have a gerbil that has it on the fingers, the
mouth/throught, AND above the nostrils is a fire pattern or white, is this
normal?  Can black gerbils have white where every they want?  Also my lil'
Mrs. B has a little on the tip of her tail.
