Here's why:
* Incorrect medication: What's safe for humans can be dangerous for cats.
* Dosage: Even if the ointment is safe, the wrong dosage can be harmful.
* Underlying condition: A veterinarian can diagnose the cause of the issue and determine the best course of treatment, which might not even involve an antibiotic.
Please reach out to your veterinarian or a qualified animal care professional for advice. They can provide the safest and most effective treatment for your cat.
