The Only Mesh Harness That Won't Damage Your Cat's Fur.


Most mesh harnesses abrade and mat fur. The Kitty Holster® Koolnit Mesh is different: athletic mesh on the outside for maximum airflow, soft 100% cotton muslin lining on the inside to protect your cat's coat.

Invented by a scientist, tested by rescues. As featured in Women's Insider.

Every order includes our signature training guide, "How to Train Your Cat to Walk on a Leash."

  • Cool Outside. Gentle Inside. Unlike cheap mesh harnesses that rub fur raw, ours features a breathable outer mesh layer with a protective cotton muslin lining—delivering cooling comfort without the friction.
  • All the Security. None of the Overheating. Our veterinarian-recommended wraparound design in a dual-layer construction that keeps cats secure in hot weather, thick coats, or active outdoor adventures.
  • Handmade Quality You Can Feel: Handmade in the USA with adjustable Velcro closures and even pressure distribution across the chest. Trusted by 50,000+ cat owners who refuse to compromise on comfort or safety.

How to Fit Your Kitty Holster Safely

  1. Measure your cat: Measure girth around chest behind front legs for proper size
  2. Introduction: Let your cat see and smell the harness for several days
  3. First fitting: Place harness on cat indoors in a calm environment
  4. Adjustment: Adjust Velcro closures for snug but comfortable fit - you should not be able to easily slip a finger underneath the collar
  5. Practice: Let cat wear harness indoors for short periods before outdoor adventures
  6. Gradual training: Start with 5-10 minute sessions, gradually increase duration

Safety Tips:

  • Always supervise cat while wearing harness
  • Never leave harness on unattended cat
  • Check fit regularly as cat grows or weight changes
  • Avoid extreme heat even with mesh - provide shade and water
  • Keep away from dogs and other potential threats

How to Care for Your Koolnit Mesh Harness

  • Washing: Machine wash cold, air dry recommended (preserves mesh integrity)
  • Inspection: Check Velcro and stitching regularly for wear
  • Storage: Store clean and dry away from direct sunlight
  • Replacement: Replace if Velcro loses grip or mesh shows significant wear
