You can find kefir made from sheep, goat, cow, any old milk. I've seen several brands of it in my HFS. Several companies on the Net sell "kefir grains" or starter cultures -- these are not "grain," but ready-made bacteria in a culture medium to use in making your own kefir. Here's a brief fact site, with a link for buying the starter.
It seems that people have made fermented products such as kefir for millennia, using the milk of the handiest mammal. The ancient Scots made kefir from the milk of sheep. Like the cultivation of grain, it is possible that the practice of fermenting milk began and continued largely for the purpose of producing alcoholic drinks. Nomadic Mongols did not sit around waiting for wheat or corn to grow -- instead, their animals offered the raw materials. Koumiss (or "kumiss") is one such product, made from mare's milk. Drinks for everybody! :->
