High Quality and Very Secure
The first thing I noticed was how premium everything feels. The Velcro holds extremely well, the buckles are sturdy, and the fabric is soft against my cat's fur. It took just a couple of minutes to adjust the fit, and now she walks around comfortably without trying to escape. I highly recommend it.

Exactly What We Needed
We wanted a safe way to let our indoor cat experience the outdoors, and this harness has been perfect. It's easy to adjust, lightweight, and fits securely without making her uncomfortable. She now enjoys sitting on the patio and exploring the backyard. Couldn't be happier with our purchase.

My Cat Loves It
I wasn't sure how my cat would react because she's usually picky about wearing anything, but she adjusted much faster than I expected. The harness fits snugly without restricting her movement, and she seems completely comfortable walking around in it. We've already been on several outdoor adventures together.

Excellent Quality Harness
The materials feel soft but very durable. The stitching is solid, the Velcro is strong, and the buckles feel secure. My cat adapted to wearing it after only a couple of tries, which honestly surprised me. It gives me confidence every time we go outside together.

Product is well made, and really good quality. Unfortunately, it’s too big for us.
Binx is still getting used to harness so we have not been outside yet! Little steps. However I do need to return the 2x size. Not sure how to do that. Any info would be helpful. Thank you
This was our first time getting our cat a harness, and we couldn’t be happier with it! The quality exceeded our expectations, and it gave us the confidence to safely take him outside on little adventures with us. He seemed comfortable wearing it, and it fit him really well. Plus, he looked so handsome in it!
When I ordered I ordered a one for a 10 lb cat but when it arrived it was too big. I contacted the owners and they shipped me a new one that was smaller. It fits beautifully and I am very glad of the service that I received.
My Cat loves the outdoors now.I feel safe to take her out.
She's loves the balcony too.
I feel secure that she's with the harness and theLeash.
Very satisfied
Although this harness/vest and leash is meant for kittens, I have been able to use it on my pet rabbit. I was able to put it on him without the help of my husband which was a major plus for me. The Velcro on top allows for adjusting to the right amount of tightness around my pet’s body. This harness allows me to be able to safely take him out to our yard to get sunlight. He was able to move without restrictions. I love the colors- baby blue and light pink!
Really happy with this harness. It feels secure, the velcro is super strong, and the quality is noticeable right away.
My cat is still getting used to it, but already looks comfortable excited to try our first walk soon
I was excited to try the harness on my cat because he is an inside cat who desperately wants to explore the outside. Upon unboxing I found the harness to be of great quality. The whole harness is padded and I trusted the Velcro and clip to keep it secure to my cat. The best part was seeing my cat roam around outside without the fear of him running away or the hassle of wrangling him back into the house!
The harness is for a kitten which is not what I ordered... and when I asked to return them they avoided my emails and kept stalling the return. Never gave returning info! Very poor quality and customer service!!
Call credit card company to dispute charge next.
The calmly paws team was incredible and kind. They sent a new harness to us when the first one didn’t fit (my fault). Make sure to measure before buying! The harness was a little big in the chest area for our cat, but fits well overall and seems very secure! The quality seems better so far than other harnesses we’ve tried for our cat! Hoping this will last a while! Thank you calmly paws!
Cat got out of harness each of the 3 times i put it on her! Yes, it was adjusted correctly. Yes, correct size for cat. So disappointed. So sad. I was so hopeful each time.
I bought this because I want to be able to take my fur babies out with me. I used the smaller one to take my kitten to the vet. Worked great. Only problem with it was that the vet tech put it on wrong and I didn't notice it until we were halfway home. The trip going to the vet was very smooth but coming home was a struggle. So please make sure that you have it on right.
It is easy to put on and it's hard for my cat to get out of. Love the colors that you offer and hope others will buy it too. The slide in with his front paws bring it up to the top velcro it secure it and we're ready to go.
Order 8159. I believe I ordered 4. Only 2 came. I suppose since I haven't heard from you in a month I will have to give you a poor review. I will wait one more week for you to respond
It took some coaxing wearing it just a few minutes a day then increased her wearing time until she was comfortable. Love this product and will order again
We initially received the wrong size, way too small. After providing chest and neck measurements a Large size was sent. My wife managed to get the Large harness on Frank which he immediately, to quote my wife, "walked out of it". Maybe it should have been a Medium?
Our kitty has a broad chest. She doesn't sit with her paws together but 5" apart!! So other harnesses or halters did not fit. This was a perfect fit for her. Thank You!
The harness is great but I am still trying to get my cat into the harness. I’m taking it slowly. The first day I got it out of the package he ran the opposite direction 😞He now sniffs it and is curious but not ready to put up it on. Not sure if he’ll ever be ready. I’m regretting I bought two of them at this point
