Exocrine pancreatic insufficiency (EPI)
Almost all cats will suffer from diarrhoea at some point in their lives. In most cases this lasts no more than a few days and generally gets better without any treatment. However, in a few cases the diarrhoea is due to a more serious underlying cause and does not resolve. EPI, although uncommon in the cat, is a condition that can cause chronic diarrhoea by reducing the ability to digest food. This means that an affected pet will suffer from chronic diarrhoea and be significantly underweight. Cats with EPI have a good appetite but despite consuming lots of food they are literally starving. Your vet is best placed to advise you on any illness in your pet so if you are worried about your pet's health a visit to the vet's surgery for a check over is always warranted.
