Feline pneumonia generally requires treatment for about a month. The specific length of time needs to be determined according to the cat's physical condition and the cause of the pneumonia. If the condition is not serious, it can be fully recovered within a month. If it is serious, it will take more than a month. Feline pneumonia requires antibiotics and anti-inflammatory injections, usually one week as a course, and then another one to two weeks of anti-inflammatory drugs, and finally a week of maintenance to cure the disease. If the cat is weak and is infected with other diseases, the treatment process will be longer.
