Feline stomatitis is one of the most painful conditions affecting cats, causing severe inflammation of the entire oral cavity that makes eating agonizing and often requires full mouth extraction for resolution.
Feline stomatitis causes some of the most extreme oral pain documented in companion animals. The diffuse inflammation affects the entire mouth - every tooth surface, the gums, the soft palate, and the throat. Eating becomes agonizing, yet cats must eat to survive, meaning they experience intense pain multiple times daily just to maintain basic nutrition. The condition causes visible suffering: cats cry when their mouths are touched, drool blood-tinged saliva, and lose dramatic amounts of weight from pain-reduced food intake. The contrast between pre- and post-extraction quality of life in affected cats is among the most dramatic welfare improvements achievable in veterinary medicine - cats literally transform from pain-ridden and skeletal to playful and comfortable.
