Actually, harnesses can be great or horrible depending on how the kitty perceives it.

In my experience, my family Siamese cat looked at the harness and laughed at it! Now with Nakita, she takes to it quite well and we will be using it when we take her to the cottage in the summer.

Also, many friends have found their kitty's absolutely adore them! They sometimes even bring the leash to the owner's feet begging to be walked like a dog. Also, leash training is great if you have a cat that has too much energy to be stuck indoors and can use some of this energy up during exploring the great outdoors.

The best harness I found was a piece of material that wrapped around the body of the cat (between the front and back legs). Therefore, nothing is on the neck and there is not chance of the cat hurting itself. Simple idea but it works!
