Animals consume water, and they urinate. The moisture is evaporated by the sun, thus making clouds. Clouds are made out of evaporated water, and when they get full it rains and the cycle continues.
Animals contribute water mainly through breathing, perspiration and urination. When droplets of sweat evaporate from the surface of an animal's skin, they take a bit of the animal's body heat with them. They also turn into water vapor and enter the water cycle, just like water evaporating from plant leaves. Clouds are created when water vapor, an invisible gas, turns into liquid water droplets. These water droplets form on tiny particles, like dust, that are floating in the air.
