We've designed the Come with Me Kitty Harness and Leash to help enrich your cat's life with the sights, sounds and smells of a safe out-door experience. It allows you to share enjoyable walks, exercise, and playtime outside your home. More quality time together leads to a deeper more fulfilling relationship for you and your cat! The harness is designed to give you gentle, comfortable control of your cat or kitten. Patent-pending design allows for a gentle pressure on the leash to cradle your cat, thus, restraining any forward motion without putting pressure on the delicate throat area. Sizing: Small - for cats with a 9 - 11 inch girth Medium - for cats with a 10.5 - 14 inch girth Large - for cats with a 13 - 18 inch girth
