DIARRHOEA is defined as the passage of soft, semi-formed or liquid faeces at an increased frequency and may occur as a consequence of several pathogenic mechanisms; specifically, osmotic retention of water within the intestinal lumen, hypersecretion of ions and accompanying water into the lumen, exudation of blood serum proteins and tissue fluid, or disordered intestinal motility. This article outlines the diagnostic and therapeutic approach to acute diarrhoea in the cat and then goes on to discuss, in greater depth, the most common intestinal diseases in the differential diagnosis of chronic diarrhoea in cats.
