Chronic gingivo-stomatitis

Feline chronic gingivo-stomatitis is an inflammatory condition affecting the mouth. It has also been called plasma cell stomatitis-pharangitis, chronic gingivitis/stomatitis, lymphocytic plasmacytic gingivitis stomatitis and chronic stomatitis. It causes inflammation of the mouth and gums and can result in pain on eating, dysphagia (difficulty on eating), weight loss, halitosis (foul smelling breath), ptyalism (excessive salivation), pawing at the mouth, and reduced grooming. The cause remains unclear, and may relate to a number of different factors including various infectious agents (eg, feline calicivirus, feline immunodeficiency virus, feline leukaemia virus), dental disease, dietary hypersensitivity, genetic and breed factors. Siamese, Abyssinian, Persian, Himalayan and Burmese breeds have all been cited in the literature as being predisposed.

Congenital liver (portosystemic) shunt

It has been reported that Colour Point Persian and Birman cats are predisposed to a vascular anomaly by which the blood from the intestines by passes the liver, a so called portosystemic shunt. However, portosystemic shunts have been seen in many breeds of cats, and most cases are diagnosed in young animals, with the severity of clinical signs being highly variable. Cats with portosystemic shunts frequently show neurological signs (due to hepatic encephalopathy) including bizarre behaviour, ‘star gazing’, head pressing, seizures and intermittent blindness. These signs are usually present in cats by 6 months of age. Affected animals will often have a small stature and may hypersalivate. Some cats will also have signs of gastrointestinal disturbances.
