Veterinary questions? Ask a Vet for Answers ASAP
Hi, Welcome to Just Answer. I'm Chris, a small animal Vet based in the UK. I am reviewing your question and will get back to you as soon as possible
Sorry to ear this. It sounds most likely that an infection is brewing from the initial injury. Cat fight wounds do tend to become infected usually 3-4 days post injury.
A visit to the vets as soon as practically possible will be needed as antibiotics are commonly required for this type of issue.
I hope that answers your question? Please let me know if you need any further help or advice.
If you have a prescribed antibiotic then yes you could start tonight pending a Vet visit tomorrow.
It is very important to always complete the course of antibiotics prescribed.
OK that's fine, you can give one twice daily until you can get home to the vet.
You're most welcome
