Weight loss and muscle wastage are usually seen in assosiation with EPI. Diarrhoea and steatorrhoea are also common.Cats presenting with EPI may also have concurrent Diabetes mellitus. Cats may present with a wet, greasy looking body coat particularly around the perineal area this may be as a result of fatty stained soiling or EPI may have a greasy and generally poor body coat

Weight loss and muscle wastage are usually seen in assosiation with EPI. Diarrhoea and steatorrhoea are also common. Cats may present with a wet, greasy looking body coat particularly around the perineal area this may be a result of fatty soiling or secondary to cobalamin deficiency. Cats with EPI may also have concurrent Diabetes mellitus.

Serum concentrations of cobalamin are often decreased. Serum folate concentrations may also be decreased due to concurrent [[Inflammatory Bowel Disease|Inflammatory bowel disease]] or Intestinal lymphoma.

The most sensitive and specific test for the diagnosis for feline EPI is the '''fTLI''' serum assay. The values are greatly reduced as compared to normal animals. Values '''<2µg/l''' in cats are considered diagnostic. This test must be carried out after withdrawing food for several hours.

The most sensitive and specific test for the diagnosis for feline EPI is the feline trypsin-like immunoreactivity assay('''fTLI'''). The values are greatly reduced as compared to normal animals. Values '''<8µg/l''' in cats are considered diagnostic. This test must be carried out after withdrawing food for several hours.
