Easy Step-In Fitting

Our unique design eliminates the struggle of pulling gear over your cat's head. Simply place their front paws in the openings, wrap, and secure. It is perfect for sensitive cats who dislike traditional harnesses.

Size Guide & Fit

Available in five sizes from Small (up to 5lb) to XXL (up to 29lb). To ensure the best fit, measure your cat's chest girth and refer to our weight categories. The adjustable back strap allows for a custom, snug feel.

Cleaning Instructions

Keep the harness looking fresh by popping it in the washing machine on a gentle cycle. We recommend using a mesh laundry bag and air drying to maintain the integrity of the breathable mesh fabric.

VS

Measure your cat's weight and chest girth. Our sizes range from Small for kittens under 5lb to XXL for large breeds up to 29lb.

Our harness features a dual-security closure and adjustable straps designed specifically to prevent backing out, making it escape-proof when fitted correctly.

Yes! Every harness comes with a matching leash to ensure you have a complete walking system right out of the box.

Not at all. We use a specialized breathable mesh fabric that allows constant airflow to keep your kitty cool and comfortable.

Absolutely! You can hand wash it or put it in the washing machine on a gentle cycle for easy maintenance.

We recommend sizing up if your cat is between sizes, as the adjustable strap can be tightened for a snug fit.
