The New York Times recently reported that Chicago residents are increasingly keeping pygmy goats in their back yards, joining chicken coops and beehives as elements of new urban farm life. Pygmy goats grow to two feet in height and 50 to 100 lbs.
They provide milk and cheese (for some reason, it is illegal to sell these in Chicago) and they can also mow the lawn and provide fertilizer. There was also an article over two years ago about pygmy goats being legal in Seattle. Clearly, they are also adorably cute!
