Harness Sizing

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

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!
