My cat came home with a closed wound near his left ear that was swollen. Tonight a large amount of pus came out of the wound. I cleaned it up and used a human antibiotic. He is very uncomfortable. What can I do?
It sounds like your kitty may have an abscess; this could be resultant from trauma such as a cat bite or scratch. Another differential would be a mass or tumor. It is recommended that your cat be seen by a veterinarian and given proper medications and treatment. Some human antibiotics can be very toxic to cats. Once he is evaluated by a veterinarian they will be able to diagnose an abscess or if they are concerned it is a mass or tumor they will recommend the proper diagnostics to work up the case.
