Measurement is done around your cat's chest. You want your cat's harness to be snug and fitted so they can't get out of it. When you take the measurement, make sure you're getting close and tight up against your cat -- down past all the floof!

If you're between sizes, go for the bigger size if your cat is still growing, or the smaller size if they are not.

Safe and secure

Cats cannot wiggle out of this great harness. We appreciate the safety features, and enjoy walking our cat with the harness.

Well made, comfy.

My deaf boy DJ loves road trips, and going to town. Wanted a nice harness that was comfortable, and that he won’t get out of if there was ever an emergency.
It’s very well made, quality D rings. Easy to figure out and adjust. He felt very comfortable in it.

Great substitute for a victorian collar

My 19lb cat got his plastic cone off after having his glands expressed. I put the harness on to take him back to the vet and discovered he couldn't reach his back side wearing it. He was much calmer and now he's healing nicely. He can lick his shoulders. This is a great invention. It's much easier to carry him to the carrier in the car when he's wearing the harness too. It's wonderful.

No Escaping!

What I love about this harness is that she really cannot get out of it. I just got a kitten and she is harness training, which means she rolled around a lot at first trying to get it off. No matter how hard she tried, she could not get it off. It stayed put! After about a week of harness training, she loves it and loves being able to walk around! Very pleased with this purchase.

I absolutely love this harness. A size small fit my 9lb cat perfectly, with a little room to bare. She walks on it just fine! I’m so pleased with this purchase, and I will be glady buying more items from Jackson Galaxy soon! Thanks Galaxy, you’re the best!
