Open up a whole new world of harness adventures for you and your cat! The Gatsby leather cat harness is a comfy & secure cat harness that can take you and your cat on adventures of all shapes and sizes - whether you’re exploring nature, crossing town to the vets, or just hanging out together in the backyard.
Th Gatsby leather cat harness is crafted from luxurious genuine leather that will last a lifetime but is so soft and supple your cat will soon forget they even have a harness on.
This harness was designed with the help of a team of escape-artist cats around the world who tested each harness prototype to escape-artist destruction! With their help, we pioneered the unique Gatsby cat harness design, which blocks off all of the favoured methods of escape (including backing out) to create a safe cat harness that's secure as can be.
Please note: the Gatsby 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 Gatsby cat harness and kitten harness is specially designed from the ground up, just for cats! Its natural scent helps your cat accept their harness with ease, while the simple single buckle step-in design means that there’s no need to put anything over your cat's head or disturb them with loud and scary velcro. Just pop your cat's front paws through the harness loops, clip up the single buckle, and you’re ready to go!
The unique sling design cradles your cat in all of the right places, while leaving their neck completely free - we hear from a lot of asthmatic kitties that it works much better for them than other harness designs because of this!
With 3 body sizes to choose from and 4 fully-adjustable straps, getting that ‘just right’ fit couldn’t be easier. To find your cat's perfect Gatsby size, simply take a look at our size and measuring guide here.
The Gatsby 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 the right size Gatsby for your cat, simply follow our size and measuring guide here.
You can also find answers to some of our common sizing questions below!
What if my cat is 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.
Are your harnesses adjustable? Will I need to buy a larger size as my cat grows?
All of our harnesses come in three sizes (small / medium / large), and each size has a range of adjustability on both the front and back straps.
There is a LOT of adjustability in all of our harness sizes, so there is a very good chance that you will be able to use a single size and adjust it as your cat grows. Obviously this depends on your particular cat and how much growing they will do - but as an example, one of the models on our store, Lola - still wears the 'small' size Gatsby harness that she first wore as a kitten, even though she is now 4 years old and fully grown.
I know my cat's weight. Can I use this to choose their harness size?
The secret to success with the Gatsby harness is getting the fit just right! We've designed a harness that comes in three sizes to accommodate every shape and size of cat. However, we've found that weight alone isn't accurate enough to choose your cat's perfect size.
Instead, to ensure the perfect fit for your cat's Gatsby harness (which is really important for your cat's comfort and safety), you need to take justtwo simple measurements.

Q: What is the difference between the cork Gatsby harnesses and leather Gatsby harnesses?
The Gatsby harness comes in two materials - natural genuine leather, and vegan cork 'leather'. They are both equally supple and strong. The only difference between them is their water resistance. The leather Gatsby harness is splashproof, whereas the cork Gatsby harness can handle full immersion. So if your cat loves to swim or you live on or around water, we'd recommend opting for the cork Gatsby harness over the leather!
Q: Do you have any advice on how to harness train my cat?
We're always on hand with tailored help and advice to help you get your cat exploring happily in their Gatsby harness! If you're just starting out, we recommend starting with our handy guide to training your cat to walk on a harness and leash: How To Harness Train Your Cat.
If you still have any questions at all, simply drop us an email at email@example.com, tell us a little about where your cat is in their harness training journey, and we'll be delighted to help out!
Q: I have a Chihuahua / small dog - is the Gatsby harness suitable for them? And how do I find the right size?
The Gatsby harness is designed for cats but we do know of several small dogs that have fallen in love with the Gatsby! You can measure your dog up as per the size & measuring guide, but just remember that these measurements are for a snug, body-hugging fit. If you'd like your dog to have a looser fitting harness or room to put a jumper on underneath, simply add on a few centimetres or inches to the measurements you've taken.

Mongo is loving his outside adventures with his new Supakit harness. Easy on/off and doesn’t fight us anymore to put it on. Walked naturally with it on after only a few minutes. He patrols the yard perimeter every day.
Kona took to the harness like she'd worn it forever! It is so easy to get on, and a breeze to adjust. We love it! You can thank Dean and Nala (1bike1world) for sharing where Nala's harness came from.
This harness makes me feel settled that he’s not getting out of it, he loves to go out. It’s a bit of a fiddly job getting it on him as he’s a very independent cat and doesn’t like being mauled with.
I’ve had to cut some of the front panel (either side of his front legs) as he was walking uncomfortably, however he still does walk strange but I’m sure the leather should, in time, mould to his shape to help him walk a bit easier. Maybe he’s just not used to having something in between his legs! I’m not giving up though, he goes out everyday. The harness itself is really well made and looks really good.
This is Moose and his new Supakit ‘The Gatsby’ harness in black. It is easy to put on/take off and is so comfortable, he naps in it. It is also fully adjustable and even fits over all his shirts! This lightweight, comfortable and high quality harness is what we’ve been searching for in all the other harnesses we’ve tried. Now we just need ALL the colors :D
This harness has been great so far! I love the single-buckle closure, and how easy it is to use. Taking it off one handed is a breeze. It seems very high quality and sturdy. We’ve only been out a few times, but it seems very secure on our kitty Iskierka!
Very stylish, the material is perfect. If this worn out in future, I’d definitely buy a new one from Supakit!!
Hi all, Love the Harness. Picked-up a bell and a name tag too. All top quality and love that the Harness is sooo lightweight. I wish I had ordered the leash (but I'm sure I will later). Now I just have to pick-up my new kitten "Monkey". (yay!!) Photo to come...
I love the harness and now my cat, Tank, is feeling pretty awesome in it. Here he is showing it off!
The harness looks beautiful on Tank but he's not so sure yet. It's so easy to get on him (all 21 pounds). It's only day two that he's worn it but he won't move around in it yet. Please note he never had anything on him since a kitten, four years ago. Nothing fit him properly. But...this does! He's better today with it on than he was yesterday! Tomorrow will be better!
The Gatsby is stylish and durable! I love the black harness and leash on my little girl and she rocks the look. It also only took about 3 days for her to get used to the feel. Highly recommend!
I am very happy with the new harness and collar and I can put it on her by myself. She is walking quite well now and comes running when I get her harness & leash out. The staff at Supakit has been very helpful.
Only four days into harness training and our Storm is already used to moving around in it. I have been searching for the perfect harness to take her out for walks in the city’s parks. Regular harnesses worry me due to the possibility the cat has to wiggle out (dangerous when outside) but also the pull back caused by neck straps is something I definitely did not want.
The Supakit harness is made by putting a lot of thought into the design; comfortable to wear, no wiggle out, no pull back, high quality materials and it looks so classy.
Thanks a lot for this. X
Artemis absolutely loves it outside!! Watching the birds
I spent countless hours searching for the best harness.
This is the one!
Real leather. Real brass.
An aura of royalty that comes across with utmost elegance.
Here is NEWMAN showing it off on the first day of use.
After trying several different harnesses, I found the one! The quality is unmatched and my cat could not escape out of it. So happy with this purchase!
The ONLY harness Prince hasn’t escaped from! Just have to get it adjusted properly. I will order every color!
Very comfortable, easy to use with adjustable straps. Stylish and very high quality! 5 stars and definitely will recommend, absolutely worth the money!
A harness is very nice and cool look.
It’s so beautiful! Even though you can’t always see it through her fluff.. It’s super comfortable for her especially due longer hikes and so far there have been zero escapes! I will definitely be recommending this!
I tried many different harnesses before but found that the Supakit Harness is the best for walking my bengal! It is very easy to put on, looks comfortable and my bengal barely felt it was on. Other harnesses I've tried either shifted or 'choked' the cat while walking/controlling , but the supakit harness being a chest-hold didn't have any problems! Highly recommend for any outdoor cat. :)
The chunkster is still too chunky so the harness (medium) only barely fits at its largest size, but soon she shall take over the world. As soon as she learns to stop turning into a pancake while she’s wearing it.
The Gatsby is the perfect cat harness! We were on a search for a minimalist step-in harness that featured leather and brass detailing- a pretty tall order, but Supakit delivered! I consider this harness to be a premium, heirloom piece that will last my cat's lifetime and more! My cat (13" chest girth) wears The Gatsby in a medium and it suits her marvelously. Every time my cat and I go out on a walk, we get comments and questions about where to get a harness like hers. It really is that eye-catching and looks stunning against my cat's fur. Whenever we get a new kitten, I plan to purchase another Gatsby!
This is the best type of harness I've ever tried! Super quality and easy to use!
