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.
