Hi Al, I can't think of a better name, but I must say you've captured the kitty's character very well in this image. That's a keeper for sure!
Hi Al, if it wants to stay on the ground you can say you were being ironic!
Why not "Elevated", call her/him "Ell" for short, and it might invoke thoughts of a snob too (most cats are a little snobbish, eh?)
BTW, I like the shot!
If its a he call him Bud
Likes to watch from concealed locations? How about Spike (spy K).
Catkins (they come on trees).
Nobite (as in all bark (tree) and no bite.\
Tonnes (metric) more but gotta go.

Ouch
