Gingivitis in cats is not always caused by an infection. Many times it can be an autoimmune reaction to tartar on the teeth. The inflammation get get so severe it starts to affect areas of the mouth and throat that are not touching the teeth, as well. This more severe type of inflammation is called stomatitis. In more simple gingivitis cases, which may be Mimi's case, often a thorough dental scaling and polishing to remove the tartar under anesthesia will be enough to provide comfort for several months up to years. This disease process can be harder to manage if there is internal medical disease like liver or kidney disease (which looks like has already been ruled out) or infection with FeLV or FIV viruses.
