Walking a cat is not quite like walking a dog. For a cat, a walk is more like a prowl, he will be looking around for things to hunt.
Cats are also small creature. They are not only predators - they are also prey. So their instinct when danger shows up is to run, climb a tree or hide somewhere. So, it is helpful to have someplace for your cat to hide if threatened by car traffic or an enthusiastic dog.
