Review on Adnikia Floral Dog Cat Harness and Leash Set: Escape Proof Pet Vest with Padded Handle Leash for Kittens, Puppies, and Cats - No-Pull, Adjustable, and Stylish by Katie Washington

I ordered a large for my 13 lb cat. He had never put on a harness before and when I put it on for the first time he did the typical "Lie down and don't move". After a few days of him really not liking it, things changed when I took him outside with a harness and leash. He is an indoor cat and very quickly realized that a harness is necessary to go outside. Now he lets me wear it and walks well in it.
