A cat harness can be useful for safe garden time, travel practice or supervised outdoor access, but it only works if the fit is secure and your cat is introduced to it slowly.
The best cat harness should be adjustable, comfortable and difficult for your cat to slip out of. Do not assume a dog-style harness will suit a cat.
