I never purchased tricolor hogs because of what I have read of their more restrictive requirements: they need more humidity than Westerns; they are not adapted to live on mice only - apparently they can more easily get fatty liver disease on a mouse diet (I do not know this for fact, just what I have read.) Also, they do not do well in rooms that have a larger temperature swing.

Not sure how difficult the tricolors are in reality. I love their look, but I got the more bullet-proof Western hogs instead, and I bet many others think similarly.
