In both rabbits and cats, this gene seems to express itself in a similar way. I just thought it was interesting, and am looking forward to hearing what our resident "genetic experts" have to say on the subject. 
opcorn:
In both Harlequin rabbits and Tortoiseshell cats, the color pattern is more a sprinkling of color or swathes rather than distinct spots:
When we add white from the "broken" gene we get this:
When we add white from what appears to be the "Dutch" gene we get this:
Regarding cats, I found this:
In genetic terms, calico cats are tortoiseshells in every way, except that in addition they express a white spotting gene. There is however one anomaly: as a rule of thumb the larger the areas of white, the fewer and larger the patches of ginger and dark-or-tabby coat. In contrast a non-white-spotted tortoiseshell usually has small patches of color or even something like a salt-and-pepper sprinkling.
