The ONLY time my cats are let outside is when I'm out there and they either have a harness on or are in their little pen. Even when they're in their pen, I will not let them out of my site. With Tubby & Peanut, I wasn't quite as strict about leaving them in the pen unattended because they were both old and were content to just lay and sniff the breezes. CJ, on the other hand, I don't trust, so if I have to go inside for any longer than a minute, he comes in with me, then back out with me.

I am just way too paranoid to let them out unattended, or even out without some sort of "confinement" such as a harness or pen - since we don't have an enclosed back yard.
