Koalas don`t drink water unless they are sick. And only if the leaves on trees are dry they make an exception and drink some water. Each day a koala bear eats 2.5 pounds of eucalyptus leaves. They are very picky eaters. Koalas eat the moist tender tips of the eucalyptus leaves. A meal gives a koala all the food and water it needs. Source See cute pictures of koala
