Please note: the Supakit adjustable cat harness is designed for use with a leash, under human supervision. We do not recommend the use of cat harnesses for unsupervised tethering, as it is potentially dangerous and can adversely affect the escape-proofing of the harness.

The Supakit cat harness comes in three adjustable sizes, to cater to every shape and size of cat (even little kittens and big chonky floof-monsters!). To find your cat's perfect size, simply follow the two steps below.

Step 1: Take your cat's measurements

It takes just two simple measurements to find your cat's perfect Supakit harness size! Using a tape measure (or a piece of string that you measure on a flat ruler later), take the measurements below while your cat is standing up. Remember to draw the tape measure tight enough to compress any fur underneath!

Harness Sizing FAQs

Putting your cat's Supakit cat harness on couldn't be simpler! There are no straps to put over your cat's head, and no loud and scary velcro to contend with. Instead, there's just a single buckle to fasten, and a super simple step-in design.

Here's a video showing you our two most popular methods for putting the Supakit harness on: the 'Drop + Pop' and the 'Superman'.

With thanks to our lovely meowdels Omi and Lola!

As part of the development process for the Supakit cat harness we recruited a team of cat testers worldwide that we called our ‘Harness Houdinis’ - cats who had escaped from multiple harnesses in the past! With their help we’ve been able to make a harness that tackles all of the main kitty escape methods, including backing out.

There are a few things to get right to ensure that these escape-proofing features can work well for your cat:

  1. The correct size: The Supakit harness comes in three sizes, based on your cat's measurements. Take a look at our simple size & measuring guide.

  2. The perfect fit: The Supakit harness is designed to fit nice and close to your cat's body so that they can forget it's even there. Find out more about the perfect fit here.

  3. Good leash position: Leash position is everything when out exploring with your cat! Here's how to always make sure your cat's leash stays in the safe zone.

  4. Not tethering: For your cat's safety and for the escape-proofing features to work well, it's really important not to tether your cat to a fixed point. Exploring with your cat is a joyful activity to embark on together, and the Supakit harness is designed for use with a handheld leash only.

What if the Supakit harness just doesn't work out for my cat?

We’ve all been there. We’ve tried a new harness on our cat, gone outside for the first time. They’ve gotten spooked. Wriggled out of the harness. It’s not a situation that anyone wants to be in. But we’ve discovered a harness that fits so well on our cats, Lumos & Noxie, that they can’t Houdini their way out of it: the Supakit Harness.

They are much easier to get on than our previous harness – they can just step into them and the single quick release buckle is easy to fasten and looks really stylish! All in all we are really impressed with these handmade harnesses and it’s reassuring knowing they are wearing something that fits securely and they aren’t likely to escape out of!
