Determining the Correct Amoxicillin Dosage for Your Cat

Never administer medication to your cat without first consulting your veterinarian. They will accurately assess your cat’s needs and prescribe the appropriate dose.

However, general guidelines from your vet might involve these factors: your cat’s weight, the severity of the infection, and the specific amoxicillin formulation (liquid or tablet).

Dosage is typically calculated in milligrams (mg) per kilogram (kg) of body weight. A common range is 10-25 mg/kg, given twice daily. This means a 5 kg cat might receive 50-125 mg per dose. Your vet will determine the precise amount.

Cat Weight (kg) Amoxicillin Dosage (mg/kg) – Example Range Total Daily Dosage (mg) – Example Range Dosage per Administration (mg) – Example Range
2 10-25 20-50 10-25
4 10-25 40-100 20-50
6 10-25 60-150 30-75

Always follow your veterinarian’s instructions precisely. Incorrect dosage can be ineffective or harmful. Accurate measurement is critical; use a calibrated syringe for liquid formulations. Administer medication as directed, completing the full course even if your cat seems better.

Observe your cat for any adverse reactions such as vomiting, diarrhea, or loss of appetite. Report any unusual symptoms immediately to your vet.
