My cat has a cut on his ear. He got it a couple of days ago and it seemed minor so I just thought it would heal on its own. He's now started scratching it a lot and won't leave it alone. It has fresh blood but no pus yet but I'm worried it will become infected. Normally I'd take him straight to the vets but we all have Covid! We probably won't be able to leave the house for 5 days or so. We dont have any family nearby. Does anyone know what I can do in this situation? Is there anyway I can treat the wound at home?
