1. Get a soft tape measure or a string and ruler.

  2. Wait for a calm moment and have your cat sit or stand.

  3. Wrap the tape or string around your cat's neck where the collar will go. Make sure two fingers can fit between the tape and the neck.

  4. Write down the measurement and add an extra inch for comfort.

  5. Check the Supercle Cat Recovery Collar size chart and pick your size. Don't forget, it has an adjustable strap for a perfect fit.
