Without their underwear??? (Sorry, couldn't resist a "Friends" reference...)I know people who would go in there commando style and take the cat.
I hope you can work something out, Michelle, even if it's only having someone knowledgeable about pet first aid to come out with you sometime and clean it up a bit.
I'm my mother's "go-to" girl when one of her cats gets bit by one of her other cats (happens about once every couple of years.) I keep injectable penicillin in my refrigerator and do what I can to help her kitty when she gets an infected bite. Hopefully you can find someone to help! Let us know what happens!
