Yep, tried it with Koscha and Mischief when they were kittens!
Might be worth a try if he's willing to follow you. Cat harnesses are available from a lot of places (even Ikea sells them). don't just attach a lead to his collar, thats a recipe for a lost kitty!
Get him used to the harness only first, put it on him for short periods and build up the time. Then when he's comfortable with that, clip on the leash. Let him decide his walking pace and it's best to start in the back garden which he knows. Then take it up a gear to quiet roads.
Last but not least, praise and treats will help a lot
Hope that helps.
