Blanc de Noir isn't exactly a pet, but they're plenty of fond of him at Long Meadow Ranch, up on the Mayacamas Ridge above Napa Valley. In addition to growing grapes (and much other stuff), they run some 290 head of Highland Cattle -- the largest such herd in California -- all grass-fed and free-range.  Blanc de Noir is a Junior National Champion bull and they say he's white when he's cleaned up.
