Use the manufacturer's measurement and adjustment instructions for the exact harness, then check the fit on your own cat. Body shape matters as well as weight, and a kitten's harness may become unsuitable as its chest and shoulders develop. Look for unrestricted movement and secure adjustment without pressure or chafing. Do not describe any harness as escape-proof: a startled cat may move in ways you have not seen during a calm fitting. Practise indoors in a secure space and watch the response before considering any further use.
If your cat freezes, struggles or repeatedly tries to remove it, stop and reconsider the activity rather than tightening it more. Keep identification details current and inspect clips and seams before use. A correct size is necessary, but it does not by itself make outdoor walking appropriate for the individual. Write down the harness size and adjusted settings, then recheck after growth or weight change rather than assuming yesterday's fit remains suitable.
