My cat develop a serious skin rash and i don't have enough money to send him to a vet what should do?

he lost alot of fur|||You can take him to the Animal shelter most of them have Dr's that will take care of sick pets Free.|||But some tea tree oil at the drugstore and comb it through her hair. We used this on all our animals. it will usually cure any skin conditions, mange etc. If this doesnt clear it up then you wil have to take her to the vet somehow.|||well i understand,the money thing...so call your local animal shelters and rescues,they can help you get started with treatment,it could be something simple .like a food,or just a shampoo....good luck to you and your kitty|||It could be an allergic reation to something, try giving him a low dose of benadrill and put some camomile lotion on the bald spots.
