My Boy Jasper has a lead, it was really handy when I moved to live with Carol because I could let him out of the car at Taunton Dean Services and he could have a mooch about with out me worrying that I would lose him. Also, if you travel around you can take the cat with you if it is used to a lead. They do take some training though, Jasper would lay down and try to pull against the lead at first, but he soon learned after I just dragged him along until his legs wore down to stumps. Luckily they grew back!
