My dog just got bit and scratched by a cat. There was a cat in my yard and my male Taz saw it and attacked it. The cat didn't get out of the yard for some reason. Before I could get over there Taz had it in his mouth and the cat scratched his nose and bit his ear. It's a stray cat and hasn't had any shots but Taz was just at the vet and had all his. Is there something I should clean his wounds with or just let them be but keep an eye on them?
