I have seen them before too. Maybe a good idea for a cat...a nice stroll to the mail box, or a walk around the neighborhood...but who knows, thay may stress an indoor kitty out a bit...if they aren't used to the sites and sounds outside.

We just started obedience school for Harlee, and I can see our trainer saying, and it is true, some people mistake their furkids for human kids. Now don't get me wrong, I adore Harlee and my cats, as does my trainer ( her rhodesians live in the house with her and are spolied)...but there is a point when you have to draw the line and realize that your dog is a dog and not a small human child.

I think the dog would rather be walking beside the human instead, anyway

Just my 2 cents.
