Doxycycline Dosage Calculator for Cats
The Doxycycline Dosage Calculator for Cats estimates the precise doxycycline dosage in milligrams and administration volume based on your cat's weight and condition severity. This tool helps cat owners and veterinary technicians ensure safe treatment by adjusting for kidney function and medication form. Whether you are managing a mild upper respiratory infection or treating severe tick-borne diseases, this calculator provides accurate dosing for tablets or liquid.
How Doxycycline Dosage Is Calculated
Doxycycline dosage represents the total milligrams of active medication required per dose, converted into a measurable amount of liquid or tablets. The calculation follows a veterinary standard to ensure therapeutic levels without causing toxicity.
Dosage (mg) = Weight (kg) × Severity Rate (mg/kg) × Kidney Factor
Where:
- Severity Rate: 5 mg/kg (Mild), 7.5 mg/kg (Moderate), 10 mg/kg (Severe)
- Kidney Factor: 1.0 (Normal), 0.75 (Mildly Reduced), 0.5 (Impaired)
- Administration Amount: Dosage (mg) ÷ Medication Strength
First, the tool determines the base dose by multiplying the cat's weight by a rate corresponding to the infection's severity. This step ensures the medication is strong enough to combat the specific bacterial load. Second, the dosage is adjusted using a kidney factor to protect cats with renal issues from accumulating toxins. Finally, the total milligrams are divided by the medication's concentration to give you the exact volume or tablet count to administer. This method prioritizes safety and accuracy for both liquid and pill forms.
What Your Doxycycline Dosage Means
Your result indicates the exact quantity of medication to give your cat at each administration time. This number bridges the gap between a veterinarian's prescription and the physical act of giving the medicine.
Mild Infections
For minor issues, the calculator typically outputs a dosage around 5 mg/kg. This lower amount minimizes gastrointestinal upset while effectively treating early-stage bacterial presence. Always administer with a small amount of food to prevent nausea.
Severe Infections
Results for severe conditions will approach 10 mg/kg. These higher doses are necessary for intracellular bacteria or deep tissue infections but require close monitoring for side effects like vomiting or loss of appetite.
Kidney Adjustments
If you selected impaired kidney function, the resulting dosage will be significantly lower. This reduction is crucial to prevent uremia and further kidney damage while still fighting the infection.
Important Note on Administration
Tablets can cause esophageal strictures in cats if they get stuck in the throat. Always follow a pill with 3–5 ml of water via syringe to ensure it reaches the stomach.

Monitor your cat closely after the first dose to ensure they tolerate the medication, and contact your vet if vomiting persists beyond the first day.
