Cat Harness and Leash

After years struggling with uncomfy cat harnesses that twisted as our cats walked, spooked our kitties, or were tricky to put on but all-too-easy for them to wiggle out of - we set out on a mission to create the perfect cat harness and leash. The result is our pioneering Supakit cat harness and leash design. It's the totally awesome harness for cats that you and your kitty have always dreamed of!
