Dear Twig: I saw some tiny goats at the zoo. They looked like they were full-grown, not babies. What were they? Sounds like they were pygmy goats, which are only about two feet tall at the withers (the point between the shoulder blades). Pygmy goats used to be called Cameroon dwarf goats. They came to the United States in 1959 from zoos in Sweden and Germany. Theyâre native to west Africa. Thatâs where Cameroon is. Nowadays theyâre kept by zoos, on petting farms, and as pets and show animals. Theyâre good-natured, playful, hardy and alert, according to the folks at the National Pygmy Goat Association (http://www.npga-pygmy.com/). They even can be milked (the does, that is). Pygmy goats need the right food, starting with good alfalfa hay; a draft-free shed or barn; and a safe, fenced exercise area. And they need a friend or two besides you -- another goat, a llama or a horse, for instance -- since goats are herd animals. A solo goat is an unhappy goat. Want to know more about pygmy goats? Hoof it to a library or book store. Chew the fat with your veterinarian or Extension agent. Or browse (Get it? Get it?) the Web. Baa-bye! Twig Hey Editor!
