My 7yr old cat Lu was missing for three days and i finally found her, but when i found her the left side of her face was swollen and there is a huge scab under her whiskers, but it doesn't look inflamated or anything just like a regular scab but i am still worried.I applied a topical cream called Fucidin but i am not sure if it can be used on animals, it was the only antibacterial cream i had so.......I think she got into a fight with another cat which she always does(Because she refuses to stay inside at nights), but there are some poisonous snakes on the loose not too far away from my neighborhood and i don't know if it's a snake bite for i know nothing on snakes. Does anyone have any idea whats really wrong.I don't really want to call the vet unless it is serious because the vets over here are quite expensive.Please Help!!!!!!!!
