My kitty doesn’t like clothing, collars, or harnesses in general. She only needs to use a collar and leash or a harness when going to the vet’s office. This harness is easy to get in and off since it has Velcro fasteners. This is also helpful since the two closure points can be adjusted as needed. I wouldn’t recommend this for kitties who use a harness to go outdoors (my kitty wore hers inside her carrier as an extra layer of security - the harness clips to her carrier) because the Velcro closures can be undone by a highly motivated cat. This harness was well made (my mom was an expert seamstress, and she trained me to spot shoddy workmanship), the Velcro closures are both wide and long, and it is lovely to look at. This harness/leash combo suits my cat’s needs well. She despises wearing it, but it isn’t hard to get her into it securely. My cat is around 11 pounds. She’s pretty tall so I bought the large size for her. It fits her well, though I think she could have worn a medium as well. This item is more forgiving in sizing than some of the clothing because of the Velcro closures. I wish my cat liked clothing more because she looked adorable wearing this harness.
