My cat is a small bread so adjusting straps leaves a lot of extra material but this is just my case, otherwise, harness stays well on the cat, easy to open and close (big clips) so I don't break nails and because the material is wide so the straps are not cutting into cats shoulder
My cat is so happy now he can sit on the front seat and see what's going on. He was ok in his cat carrier but he seems to love being in the car now he's sat next to me. There's a long enough lead attached so he can move around on the seat easily but it's short enough to ensure he's safe while I'm driving.
I am using this harness with my Siberian Forest cat for the past 2 years now and am very happy with it. It's very easy to adjust and to put on and I'm using it both as a cat seat belt and, together with a cat lead I bought, as a walking harness. I especially like the padded section which comes to rest on the chest, as I feel confident that the harness doesn't chave or pinch. While hearing all sorts of horror stories from other cat owners about riding in the car with a cat in a carrier, my cat snuggles up in the back, secured with the seat belt adapter, and falls asleep. Great product, happy cat owner!
I have used this harness for varying sized cats from 6 month old kitten to very large Norwegian forest cats. it is secure, easy to adjust and very sturdy. I have used it for both car and buggy trips and my cats like it far better than any other harness I have had before. it's really well made too. a really good buy. I really recommend it
