Can't decide on the best cat harness material for your adventurous feline? The Supakit cat harness and leash comes in two materials - natural genuine leather and vegan cork 'leather'. They are both equally supple and strong. The only difference between them is their water resistance. The leather cat harness is splashproof, whereas the cork cat harness can handle full immersion. So, if your cat loves to swim or you live on or around water, we'd recommend opting for the cork cat harness over the leather!
The Supakit cat harness and leash is specially designed for wriggly, boisterous cats to keep them secure throughout their adventures. We developed our harness design with the help of a team of escape artist cats, our 'Harness Houdinis', who had escaped from multiple harnesses in the past. With their valuable input, we were able to craft a cat harness and leash that addresses all of the common escape methods, including backing out. To make sure that the escape-proof features work effectively for your cat, there are a few additional factors to consider, such as ensuring that you pick the right size, achieve a correct fit, maintain safe leash position and embark on proper harness training for your cat's comfort and security. You can find more information about ensuring that your cat's harness is safe and secure in our harness escape-proofing guide.
If your cat is new to harnesses, don't worry! We're here to help. For a full introduction to every element of harness adventuring - from putting the harness on, to walking on a leash, backpack training and even managing dog encounters, enroll your cat in our Complete Cat Harness Training Course. Alternatively, if you'd like to start with the basics and focus on putting the harness on, you can try out our Free 10 Day Harness Training Bootcamp!
For safe exploration, the Supakit cat harness is designed for use with a handheld leash. You can choose from our fixed-length leashes or retractable leashes in the Supakit leash range to ensure the ideal leash setup for your cat's safety.
