I noticed my cat last night not feeling well, but he ate breakfast this morning and went outside. But he rarely moved -- all scrunched in that posture that shows discomfort. This afternoon, I brought him inside and looked at him. He had a place on his arm that he had been licking -- hair all matted down, but just a little wet. No blood. He curled up again (behavior that is NOT at all like him since he is usually animated and talking) and I finally had a chance to really inspect his arm. I got out my first aid book and it said to cut away the matted hair. When I did, I found a wound that is oozing. It is infected, and I am now putting warm compresses on it and bathing it in hydrogen peroxide (highly recommended by the author, who is a vet). Is there anything else I can do until morning? I'm worried that he will get worse during the night. I gave him some diluted chicken broth and he licked some of it, but not all of it. I want to keep him hydrated, of course. I may switch to tuna juice, but I don't want to overload his tummy and make him sick. Please advise asap. I know that cats can get really sick, really fast. Is there a vet in the house??? thank you.
