My 8-year-old cat was perfectly healthy, but she started acting sick after beginning a course of antibiotics that were given as a precaution after a minor procedure. She's been lethargic and hasn't been eating much since then. Is this a normal reaction to antibiotics, or should I be worried about these sudden changes in her behavior?

Answer

Your cat's sudden lethargy and loss of appetite after starting antibiotics can be concerning, as these medications can sometimes cause side effects, but such changes shouldn't be ignored.

  • Monitor your cat for any other changes in behavior.
  • Consult with your vet if symptoms persist or worsen.
  • Be aware of common side effects like digestive issues.

It's not unusual for cats to experience some side effects when starting antibiotics, such as decreased appetite or lethargy. However, these should be mild and temporary. If your cat is experiencing significant changes in behavior, such as prolonged lack of appetite or severe lethargy, it's important to reach out to your veterinarian to ensure there isn't a more serious underlying issue.
