Cats reaction to coconut oil

[khager]

My cat Simon has feline stomatisis. We recently found out about coconut oil and thought it might help him so 3 days ago I started giving it to him in his food. His mouth seems to hurt less, but he's sleeping a lot and his meow is really raspy. I'm wondering if this could be a negative side effect (like an allergy or something?) to the oil, or if this is part of the process for his body adjusting to it. Has anyone had a similar situation? I'm not sure whether to continue with the oil since it does seem to be relieving the pain, or take him off of it.
