Possibly dating back as far as 1600 B.C., ferrets have been long regarded for their usefulness, beauty, and charm. The Old World ferret is probably a domesticated breed of polecat, about 14 inches long, and used (at least since Roman times) for hunting mice, rabbits, and rats. The male is known as a hob or dog, the female as a jill. The calendar features these determined and inquisitive companions; so entertaining and intelligent, they capture your heart with their charm.
