　　Influenza

　　Influenza is a viral disease, usually spread through contact between cats. Antibiotics do not work on viruses, so the typical treatment is to relieve the cat's clinical symptoms as much as possible and improve the cat's own immunity with a balanced diet to protect the cat's life until it recovers naturally. However, there is a prevention method — vaccination, which can protect against influenza.

　　Cats with this disease show symptoms of a severe cold and may also have ulcers on the surface of the eyes or inside the mouth. Cats use their sense of smell to stimulate appetite, and influenza causes loss of smell, leading to reduced food intake. Some cats may never fully recover and become chronic influenza sufferers or "snufflers." Kittens are often the most severely affected, and without careful care, they may die. To help kittens resist this disease, they need to be vaccinated, and adult cats require an annual booster shot.
