Lymphocytic/Plasmacytic Gingivitis Stomatitis in Cats
In this article
Cats can suffer from lymphocytic/plasmacytic gingivitis
(LPGS) or feline gingivitis stomatitis (FGS), a condition that is unique to
their species. These terms refer to a severe inflammation that can affect the
entire mouth as well as the gums. The gums will be very red and bleed easily if
chafed. Some cats will have lesions that proliferate along the gums. Affected
cats will have bad breath and may drool a great deal. These cats have extremely
painful mouths and often will simply lick at their food, making no attempt to
pick up pieces or chew.
Although most cats with this problem are middle-aged or older, there is a
form that affects kittens just 3 to 5 months old. The kittens may outgrow the
problem with extensive care, but most older cats do not. Abyssinians, Siamese,
and Persians seem especially prone to the juvenile form of this problem.
Cats are known for sleeping long hours, but when they’re not snoozing, they can be very active. Those periods of activity often happen during the night. If your cat attempts to wake you after you’ve gone to bed, he may want to play, eat or simply enjoy your company. Young cats under one year of age in particular can drive their owners crazy from sleep deprivation!
Understand that the cat’s ancestor, the African wildcat, is mostly nocturnal. Domestication has shifted our pet cats’ activity...
The disease itself seems to be an immune reaction against dental plaque
and/or the actual dentin of the teeth (the substance just under the enamel).
The definitive cause is unknown. It appears to be an allergic or immune-based
problem. About 15 percent of cats with LPGS will be positive for feline leukemia
virus or feline
immunodeficiency virus. An earlier exposure to calicivirus is considered to
be a factor as well. The Bartonella species of bacteria are also
A biopsy may be needed to definitely diagnose this condition and rule out
other similar problems that can result from renal
cancer. The fact that the lesions tend to be bilateral and symmetrical
makes cancer less likely, but it should be considered and definitively ruled
out. X-rays should be taken to check for tooth problems, including root
resorptions (dissolving roots) and abscesses.
Treatment: Cats with LPGS will need to be treated for the inflammation with
oral or injectable steroids. Antibiotics should
be added, at least initially, to prevent bacterial overgrowth. Pain
medications, such as a fentanyl patch, can be important to keep the cat
comfortable. Laser surgery may be done to remove proliferative areas of
inflamed tissue. Bovine lactoferrin (an iron-binding protein with
immunomodulation capabilities) can be compounded for cats and used to flush the
mouth. This product may act against calicivirus, as well, so it may be a
