Do you know who owned the dog? The dog owner should pay for your vet bill.
If this were MY cat and was in this kind of condition.....I wouldn't wait. I don't understand why you're waiting. The poster above that mentioned the dog's owner should pay is right!! That dog should have been leashed, it's the laws in many states.
I hope your cat is okay? Please let us know!
Wow, I am hoping kitty's jaw isn't fractured. Was it a stray dog or was it someone's dog who attacked him? Did your cat get into the dog's backyard? Have you taken your cat to the vet yet? I hope you have an appointment by now.
