deer


A deer is a ruminanting animal. This means that it has two stomachs and digests its food in two steps.

In the first step, the deer chews up the raw material, swallows it then brings up the partially digested material, known as cud, back into his mouth and choose it again and again until it is ready to pass into the second stomach.
In the second step, the soupy cud is passed to the main stomach for digestion for its food value.

Also, male deer lose their horns every season, whereas, male Waterbuck do not lose their horns but keep them for life.
