Things You'll Need
- Prescription for Flagyl or Metronidazole
Instructions
Bring your cat to the veterinarian and allow him to rule out other infections or causes of the diarrhea.
Weigh the cat to determine proper dosage. The minimum dosage is 5 mg per pound but for serious cases can be as high as 23 mg per pound. Flagyl is only available with a veterinarian prescription.
Ask the vet how often to give the determined dosage. Flagyl is given one to four times a day depending on the severity of the cat's problem.
Administer the dosage to the cat per the prescription's instructions. Watch for allergic reactions. Contact the vet immediately if the cat shows any new symptoms or the diarrhea becomes worse.
