He or she is the friendliest kitty! Comes right up to me
when I walk around the neighborhood. I explained to the
cat that I was out experiementing with my extension tubes,
and asked permission to take a few shots.

I took this expression as a nod of approval. Have you ever
tried to get a cat -- not even your own cat -- to be still
for a moment while you got in it's face with a closeup lens?

Lemme tell you...'tain't easy!
