How to Measure Your Operative (Cat)

  1. Prepare your tools.
    Use a soft tape measure (or a piece of string + ruler).

  2. Locate the measuring point.
    The chest girth is measured just behind the front legs—at the widest part of the ribcage.

  3. Take the measurement.
    Wrap the tape snugly (but not tight) around your cat’s body. You should be able to slip one fingertip between tape and fur.

  4. Read and record.
    Note the measurement in centimetres (or inches), then match it to the size chart above.

  5. Select your size.
    If your cat’s girth falls on a boundary, choose the larger size for comfort and stealth-mode maneuvers.

Tip from Tony: Measure twice, fit once. Nothing worse than a harness that’s too tight during a midnight recon.
