My GeoLolCats

Lockwood over at Outside the Interzone has this geololcats meme going on with cats. 
I have problems with my editing photos, so here's my cat Shaddow meme picture.  The caption I would use with it is something like this:

What type of rx izz that?  Itzz sedimentary.  I can c the sand grains!

Shaddow is an out door cat and he's hard to see unless he's hungry.  It took awhile for him to show up for me to get this picture.
PS I know his name is spelled wrong but that's how we spell his name.
