The small intestine has a small diameter as indicated by the name and has a length of 2 ½ times the body of the cat. It extends from the stomach to the large intestine. The food that leaves the stomach and enters the small intestine is mixed with pancreatic and gall bladder secretions. These secretions break the food down into smaller subunits to allow the absorption of sugars, proteins, and fats. Any problem in the intestine can cause vomiting and watery diarrhea. Causes for the small intestine disease include:

  • dietary intolerance
  • ingestion of a foreign body
  • intestinal parasites

Small intestine disease symptoms can be secondary to a major underlying health condition like hormonal imbalance, hyperthyroidism, and organ failure.
