Fluffy going for walk

We live on the third floor so Fluffy can only go out when we take here (about once a day). she loves being out in the morning and in the evening. In the middle of the day there is a little to much noise and kids running around. Our two other cats, Scott and Dexter, are to scared to go out.

Here favorite things is watching birds, chasing insects and smell cars. What is it with cats and cars? Every cat I have had, have enjoyed smelling cars.
