- Calculate the Dose: Multiply your cat's weight in pounds by 1 mg (or weight in kg by 2.2 mg) to find the total mg needed.
- Convert to ML: Using the concentration (12.5 mg/5 ml), calculate the volume. The formula is:
(Cat's Weight in lbs * 1 mg) / 12.5 mg * 5 ml. As an example, for an 8 lb cat:(8 * 1) / 12.5 * 5 = 3.2 ml.

Steps for Safe Administration
- Confirm with Your Vet: This is the first and most important step. Get a prescription or explicit dosage instructions from your veterinarian.

- Draw Up the Dose: Using the syringe, draw the exact amount of liquid calculated from the chart.
- Administer the Dose: Gently open your cat's mouth and squirt the liquid into the cheek pouch. Do not force it if they are struggling. You can also mix the dose with a small amount of food or a treat if your cat will accept it.
- Observe for Side Effects: Common side effects in cats include drowsiness, dry mouth, and gastrointestinal upset. If your cat becomes excessively sedated, has difficulty breathing, or shows signs of vomiting, contact your vet immediately.
