A broken jaw should def be seen by a specialist, pain meds and antibiotics aren’t going to heal it, your cat will end up deformed and in a ton of chronic pain. I would personally look into low cost clinics and care credit. It’s a medical credit card that you can use. Usually no interest if you qualify. If there’s a vet school around you, they will work with you on payment. Her jaw won’t stay the same. She’s likely comfortable just right now bc of the pain meds but pain meds shouldn’t be given long term.

Hey I’m so sorry to hear about your cat. I 100% agree with @momgroupreject, she should be seen by a specialist. I know it will get expensive but that’s the best chance she will have at a full recovery and not being in pain. Check into the care credit card and any vet teaching hospitals around u. For now the pain meds and antibiotics are a good start but won’t help much in the long run. She will likely need surgery to reset the jaw. If this happened to a human it’s basically the same thing they would do for us. Good luck and u can private message me if you’d like. Keep us posted
