Supakit Size Guides

Collar Size Guide

We have two kinds of collars for you to choose from - 'kitten' and 'adult'. Each one has a unique breakaway safety buckle tailored to your cat's weight:

Cats Weighing 2.2 lbs - 5.5 lbs

Adult Cat Icon
Cats Over 5.5 lbs

Choose the kitten collar Choose the adult collar

It's really that simple! There's no need to measure your cat's neck for a Supakit collar – they're designed to be fully adjustable, ensuring a comfortable fit for cats of any neck size. Curious about the specifics? You can view the exact dimensions of our collars here.

Helpful Hint: As your kitten grows and crosses the 5.5 lbs weight threshold, it's a good idea to switch to the adult collar. This reduces the likelihood of collar losses. Learn more about this transition here.

 

Harness Size Guide

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 pick 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!
