Cephalexin for Cats Calculator

Ensure your cat gets the right amount of medicine. This tool uses feline weight to calculate the precise milligrams of Cephalexin required for common infections.

Feline Dosage Calculation: 1. Unit Conversion: If in lbs, Weight (kg) = Weight (lbs) / 2.2046. 2. Dose Formula: Total mg = Weight (kg) × Dosage Rate (mg/kg). 3. Administration: Dose is typically given 2-3 times daily (every 8-12 hours). Standard Feline Rate: 22 mg/kg is the common baseline for skin or urinary tract infections.
Scenario: A 10 lb domestic cat requires Cephalexin for a urinary tract infection at a standard rate of 22 mg/kg. Calculation: 1. Weight in kg = 10 / 2.2046 ≈ 4.54 kg. 2. Dosage = 4.54 kg × 22 mg/kg = 99.88 mg. 3. Rounding = Common liquid suspension is 100 mg per mL. Result: The recommended dose is approximately 100 mg (or 1.0 mL of 100mg/mL liquid).
