Hi I have a 10 year old Siamese male cat. He always had bad teeth but recently started clawing at his mouth. Now he has a pretty bad wound on his lip which swelled up. He obviously can't eat dry so I been feeding him soft which has been eating. I just don't know what to do, I have absolutely have no money for the vets and would hate to put him down, he is still young and healthy cat. I been trying to clean the wound with peroxide.
