Diatomaceous Earth Benefits for Pets

My cat was miserable and his ear stank. I put a pinch of diatomaceous earth (swimming pool filter grade)in each ear. He seemed to be a bit better in about 40 minutes. He has stopped shaking his head and seems less lethargic. We'll see if he needs something more, (if he has a bacterial infection. His ear smelled like feces. ewwwwww!
