Pets need food as ‘fuel’ to stay alive. In order to digest food, it needs to be fractured into small pieces (nutrients). Before food can be absorbed by the body, it needs to be broken down into smaller parts (nutritients) This process, called digestion, takes place in the digestive tract and other organs. It starts in the stomach and continues through the small intestine, where nutritients are absorbed into the blood. Liver and pancreas produce juices that enable digestion to take place. In the colon there is little digestion. Water from the colon is being extracted and recycled back into the body, leaving a dry and solid mass. This is important to get solid and dry faeces. It also maintains the volume of body fluids.
