Chronic mucosal inflammations in the mouth of the cat, occur at all ages. Often the problems start at an early age (under two years old), but most problems occur in middle-aged cats (7-8 years old).
The complex consists of 3 diseases that can occur together or separately:
Gingivitis or gum inflammation:
In gingivitis, the gums are swollen, red, and bleed easily. These inflammations spread an unpleasant odor, which can make the cat stink out of its mouth. As a result of the inflammation, the gums may retract, making the dental neck and roots visible. When the inflammation is so extensive that the underlying bone also becomes inflamed, it is known as periodontitis.
Stomatitis or inflammation of the cheek mucosa:
As a result of tartar, the mucous membrane of the cheek may become inflamed. This occurs mainly at the molars where tartar developed is. The stomatitis in gingivitis – stomatitis – pharyngitis – involved does not remain with a small local inflammation at the level of a tooth. The inflammation can spread over a large part of the mucous membrane of the cheek.
Pharyngitis or mucosal inflammation of the oral cavity:
The mucous membrane at the back of the oral cavity becomes inflamed. In particular, the soft palate and the mucous membrane from the upper to the lower jaw at the back of the mouth can become extremely inflamed. This process is very painful for the cat, and they will often stop eating. This very severe inflammation of the oral cavity is also called faucitis and is characteristic of the complex.
