  • Fully adjustable on all four straps, so you can tailor the harness to follow the contours of your cat's body perfectly, and it won't rub or twist as they walk. 
  • Escape proof. The unique sling design and tailored fit makes the Gatsby harness completely escape proof (when fitted correctly).
  • Extra strong. Weight tested up to a whopping 18kg / 40lbs.

The Gatsby cat harness is available in three sizes (small, medium and large), which are designed to span the full range of cat sizes - from young kittens, through to the largest of adults!

Gatsby cat and kitten harness size chart



We strongly recommend measuring your cat for their Gatsby harness, to ensure the perfect fit. 

STEP 1 - Take your cat's 'front' and 'back' measurements...

Each measurement is made all the way around your cat. Use a cloth tape measure or piece of string, and make sure you draw it tight enough around your cat for any fur underneath to be compressed. 

1) FRONT: Measure from your cat's shoulderblades, around the front of their breastbone, and back again.

2) BACK: Measure from your cat's shoulderblades, around the back of their legs, and back again. The tape measure should pass behind their elbows.

STEP 2 - Compare your cat's measurements with the harness sizing chart above

If your cat is on the cusp of two sizes, please choose the smaller of the two. And if you need any advice at all with sizing, simply send us a message, and we'll be happy to help!

Ashley C.

"It is not easy to find a cat harness that is safe, comfortable and looks nice. Thank you Supakit for providing all of the qualities I look for in one perfect harness. I should also mention it is very easy to put on which Pearl and I appreciate. It's obvious this harness was designed with love for our cats."

Jackie P.

"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. All in all we are really impressed."
