Harness Sizing FAQs

  • What if my cat is between two harness sizes?
    If your cat sits between two sizes, we usually recommend choosing the smaller option. A snug fit helps keep the harness secure, while also being more comfortable for your cat, as it won’t shift or move around while they explore.
  • Can I choose a size based on my cat's weight?
    Weight on its own isn’t always the best guide, as cats of the same weight can have very different shapes. For the most comfortable and secure fit, we recommend taking the two quick measurements above so you can find your cat's ideal harness size.
