Most cats won't tolerate this, but when I realized Big was going to be too big to carry in my arms or a carrier, I began taking him to the vet on a leash. Since Noah's still young he may be easy to train. You may have to get a harness for a dog, though, because the cat ones are surely not going to be big enough. I was lucky to find an adjustable one. If Noah is real laid back, also, he should be easy to train. Big was already a year old before I tried him in the harness, but he took to it just fine. When summer is over we will likely be taking him for his "walkies" again! He trots along just like a dog!
