To find your cat's perfect Gatsby harness size, simply follow our harness measuring guide to take your kitty's front and back measurements, and then compare them to the harness sizing chart on that page.
This should guide you to which of our three Gatsby harness sizes will work best for your cat. But what if you have measured your cat up and their front and back measurements fall on the borderline between two harness sizes?
When a cat is on the borderline between two sizes we always suggest choosing the smaller of the two, as it ensures a good snug fit which will make the harness nice and escape proof (and is comfier for your cat too as the harness won't move around as they walk).
Because of the way the Gatsby harness is designed, there is a little bit of give and take between the front straps and back straps:
- If your cat needs just an extra cm or half inch at the back, you can loosen the front straps just a little to give them the extra adjustability they need at the back.
- Or, if your cat needs an extra cm or half inch at the front, you can loosen the back straps just a little to give them the extra adjustability they need at the front.
