Cow

Cows are passive mobs that first appeared in Alpha. Their main value is as a source of leather, which can be used to make the lowest tier armor, and a source of milk, for use in cake. They are 1.6875 blocks tall, 0.625 blocks wide and 1.5 blocks long.

Behavior
Cows spawn in groups of 4-12 individuals and proceed to roam aimlessly. Cows will jump up small inclines, and frequently cows may be seen bouncing up hillsides. This may lead to their demise, as cows don't pay attention to long falls and often plummet to their deaths. Like all other passive mobs, they move entirely randomly, and although it can appear that they are attracted to light, this is not the case. It is a common sight to see passive mobs clustered in lit areas at night, but this is only because that is the only place they can spawn, and they will ofter wander out into the dark. They will make no attempt to stay out of water, and may often be seen splashing about in oceans and lakes.

Appearance

 * There has been some confusion about the cow's gender due to it having both horns and an udder; however, in reality, female cattle often have horns.
 * Cows in the PC Gamer demo are branded with a 'PCG' logo on their side.

Drops
Alpha and Beta
 * 0-2 pieces of Leather
 * When a cow's udder is right-clicked with a bucket, the bucket is filled with Milk. As of Beta 1.3_01, the pink of the cow's ear may also be milked.
 * In SMP, clicking anywhere on the cow with a bucket will fill it with Milk, but only at the maximum distance at which you can use the bucket.
