My cat had a fight with one of our other cats and one of his nails on his back paw was completely removed. It bled a little but he seems fine as if there is no pain. Because we are unable to handle him due to his aggressive nature (we think he was abused prior to adopting him), we took him to the vet and they could not treat him either. Since we cannot clean it or apply antibiotic ointment, will he contract an infection and die? We are very worried.
