It's a bird! It's a plane!.. No, actually, it is a bird.
When Chimie wanders outside of her specified playground (as specified by Hans, the alpha cat), she gets a warning, then, if she does not listen, I have to get up, get her out of the bush (or wherever she's slinked to), smack her on the nose (which is, like, so embarrasing!) and carry her over to the "base".
This time, I put her on the chair, and she either liked the perch or was in her "I'll stay in one spot to show how sorry I am" mood. Either way, she stayed there for the rest of her playtime, just staring around.
