The RSPCA does not recommend walking any cat on a leash, although it is legal to take your cat on a walk on a leash under direct supervision. Tabbies are rather intelligent and can learn to walk quite successfully on a leash, but you won’t have the same experience as you would have with a dog.  While you can take a dog for a walk, the opposite is true of tabby cats. They can take you for a walk. Don’t expect to go where you want to go; instead, you will have to follow wherever your cats want to go.  Unless you train your tabby from a very young age, it will be a difficult task getting your cat to walk on a lead successfully.
