If you look in your cat’s mouth and see red around teeth and/or in the back of the throat, that may be stomatitis. Below are pictures of what stomatitis has looked like for my cat Lily. It may be worse or better in other cats, depending on how bad the disease is.
I showed these pictures to my husband and he did not understand what he was looking at because he did not know what a healthy cat’s mouth looks like. I explained to him that there should not be any red in the mouth of a cat without stomatitis. Here is the healthy mouth of one of our other cats, so you understand what a normal cat’s mouth looks like:
Below are pictures of my cat Lily’s mouth, as well as images of the signs of stomatitis that I found throughout my house from her. I am including those with the hope that they may help other people figure out what they are looking at if they see similar drool stains that may or may not contain blood. Lily only has one eye, which had nothing to do with stomatitis.
There are other websites that show pictures of stomatitis in other cats. If you want to see more pictures of stomatitis, you can visit any of the sites below.
My Pets Dentist
There are a lot of pictures showing stomatitis in various stages. Be aware that some of them are a bit gruesome (at least to me).
Punta Gorda Animal Hospital
This site has two pictures, and they have done a good job describing what you are looking at.
This site has a picture showing how stomatitis looks back in the throat. After seeing this picture it should be easy to understand why cats with stomatitis stop eating food or drinking water.
