Supakit Size Guides

Collar Size Guide

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

Kitten Icon

Cats Weighing
1 kg - 2.5 kg

Adult Cat Icon

Cats Over 2.5 kg

Choose the kitten collar
Choose the regular 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 2.5 kg weight threshold, it's a good idea to switch to the regular collar. This reduces the likelihood of collar losses. Learn more about this transition here.
