I found my two year old cat lying under a few shovels in my backyard while I went to feed her. She came out but I noticed she had a huge limp and then I saw that she was covered in dried blood. I cannot tell whether or not she was attacked by another cat or animal or if she was ran over. She is still alive, however I was wondering if whether or not giving her human antibiotics would hurt her seeing as when I went to the vet, they said the best they could do was to let her rest and eat, but she is currently not eating. So if anyone would give me some answers it would be most appreciated.
