Carru

From The unofficial Dark Sun wiki

Carru vaguely resemble cattle of Earth. One carru can provide 200-250 pounds of meat for consumption. Female carrus can also be milked, providing thick creamy milk. A female carru products 3 gallons of milk a day. The milk only keeps for a few days. All carru have a fluid sac behind their heads which contains 3-9 pints of water.
