Discover the cat harness that you and your cat have always dreamed of! Supremely comfortable, super cute and ready for every adventure. Whether you’re hopping in the car for a journey, trekking through the wilds or your kitty is just napping in the sun, the Supakit adventure cat harness will be your cat’s perfect companion through their adventures great and small.

The Supakit cork cat harness is crafted from amazing vegan cork ‘leather’, harvested just a few miles away from our workshop in Spain, to keep your kitty’s carbon pawprint low. This super-sustainable material is just as strong and supple as our regular leather range, but best of all it's waterproof too! Be sure to check out our matching cat leash for the full head-to-toebean look.

Please note: the Supakit adventure 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

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?

If for any reason you would like to return your Supakit harness, it's simple to do! We have warehouses in the UK and USA, so you can choose whichever is most convenient for you to send your return to. Please note that return postage is at the customer's expense.

The Supakit harness is designed to fit your cat snugly and securely. Here's how to achieve that perfect fit!

Harness straps


Fitting your cat's Gatsby harness


To maximise your cat’s comfort and safety, you want to ensure a snug fit! Adjust the front and back straps until the harness feels nice and secure - you want to be able to fit one fingertip only between your cat and their harness when they are in neutral standing position. Make sure that the back straps pass behind (not over) your cat's front elbows.

Achieving a good snug fit is important for escape proofing but also comfiest for your cat (the less they can feel the harness slide across their fur as they move, the more relaxed they'll be!).

Remember to adjust both left and right sides of the straps equally so that the harness stays centered on your cat's body.


Every cat is different, and some breeds may have a slightly different shape to others. However, there are some ways to tell if you’ve achieved the perfect harness fit…

The main buckle should ideally be positioned directly over your cat's shoulder blades, as this creates a perfect balance between the front and back straps on your cat's harness. It can sometimes look as though the buckle is uncomfy for your cat in this position, but don't worry, it's perfectly comfortable for them! The buckle is specially designed for kitty comfort - with a smooth surface to cause a minimal amount of friction against their fur, so that they can forget all about their harness and get on with the important business of exploring.

The chest piece should sit against your cats chest – this seems obvious – but what we mean is that the widest part of the harness should be holding the broadest part of your cats chest, this is to support your cat and distribute any pressure (because of pulling against their leash) evenly across your cats torso, making it super comfortable.

The back strap should sit snugly into your cat armpit – think of it like a backpack! The harness back strap disappearing into you cats fluffy armpit is a sign of a good fit. This means the harness is less likely to move around or rub whilst your cat is walking, also it decreases your cat’s ability to wiggle out of their harness meaning it increases their safety!  If this doesn’t look right on your cat, there is some information on how to adjust this for special cases below.

Special cases

  • My cat has been using another style of harness, and seems a little bit uncomfy or freaked out in their new Supakit harness

    If your cat has been using a different style of harness in the past, you may find that they require a little bit of time to settle into wearing their new Supakit style of harness, and get used to the new sensations of where the harness touches their body. You might like to take a look at our Harness Introduction Guide over on the blog - it's written for harness first-timers but the process is the exact same for kitties who are switching over from a different style of harness! 

  • My cat is a larger cat and I'm worried that the back straps are tight under their front legs

    If your cat is on the larger side you may benefit from changing the angle at which the back straps come down behind their elbows.

    To achieve this, you can experiment with letting the harness' front straps out a little longer, and taking the back straps in a little tighter. The end result will be that the main buckle moves further down your cat's back (towards their tail) and creates a less sharp angle on the back strap behind their elbows.

    Just remember to check that once you have made your adjustments you are able to achieve a good snug fit overall (that allows you to slide one fingertip between your cat's harness and their body when it is on).

    Try to be conservative with your adjustments - while it's OK to move the buckle so it sits just behind your cat's shoulderblades, pushing it much further back on your cat's body can prevent the harness' escape-proof design from working effectively.

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!
