Foggy

I am scared... very scared. My 13 year old cat, Fog, has a huge open smelly wound in his mouth. Poor oral care, of course. It is on his left side and the back teeth are very loose. This is going to be a whopper of a visit at the vet's office. He is laying on the sofa next to me cleaning himself, after the bath I gave him. He seems to not be bothered by the issues in his mouth. He is still very spry, loving and alert. I have to do what I can to make him better... Now will 730 hurry up! (I need to call the vet!)
