Cats don't do walks very well

So,I tried to take my cats for a walk today. Yes, yes, yes, I know what you are thinking. They are cats, not dogs. But still... You would have thought I was trying to kill them the way they behaved. Rodney sat down on the sidewalk and started yowling, and Colonel laid down and refused to budge. I ended up carrying them back to the house. Sheesh.
They don't mind the harness, or the leash. They just don't seem to like the outdoors very much. I think I will try again tomorrow, and this time use their favorite toy, a bunch of feathers on a string, to goad them into moving. Hopefully they'll equate walking with fun time. Sigh.
