Kitty Holster® Koolnit Mesh Cat Harness – Keep Your Cat Cool and Comfortable.

Most mesh cat 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 — the best of both worlds for warm weather cat walking and hot climate outdoor adventures.

---

• Cool outside, gentle inside: Breathable mesh outer layer with a protective cotton muslin lining that prevents rubbing, matting, and fur damage — unlike standard mesh cat harnesses that scratch and snag delicate coats.
• Escape-resistant vest design: Same secure wraparound fit as the original Kitty Holster — wide industrial-strength Velcro closures that are much harder to slip out of than thin H-style harnesses. Ideal for escape artist cats in warm weather.
• Perfect for heat and long fur: Developed in Texas for summers over 100°F and ideal for long-haired cats and large cat breeds that overheat easily. The go-to summer cat harness for adventure cats in hot climates.
• Handmade in the USA: Trusted by 50,000+ cat owners worldwide who refuse to compromise on comfort or safety — including anxious cats, therapy cats, and cats in training for leash walking.

How to Fit & Train Your Cat

Choosing the Right Size

For a secure, escape‑resistant fit, always measure before ordering:

• Chest (girth): Measure snugly around the widest part of the ribcage, just behind the front legs.
• Use our size chart and choose the size where your cat’s girth measurement falls within the range.

Fit tip: Adjust the Velcro so the harness is snug but comfortable. You should not be able to easily slip a finger under the collar or chest closures—this snugness is what keeps it secure.

1. Introduction: Let your cat see and smell the harness for a few days so it becomes familiar.
2. First fitting indoors: In a calm environment, place the harness on your cat and gently secure the Velcro around chest and shoulders.
3. Short practice sessions: Start with 5–10 minute wear sessions indoors, gradually increasing time as your cat relaxes.
4. Add the leash: Clip the leash and allow your cat to drag it under supervision before beginning guided walks.
5. Outdoor training: Begin in a shaded, quiet area and build up to longer adventures as your cat’s confidence grows.

Best for: Summer walking, hot climates, long‑haired cats, and any cat that tends to overheat in standard harnesses.

Every Koolnit Mesh harness includes our guide, “How to Train Your Cat to Walk on a Leash,” to help you train safely and gradually.
