Here's a couple pics of NandaDevi, aka Devi the  6 lb psycho kitty, who chases
bottle caps across the wood floors at 3 am.
 

This is her stealing her favorite prey from the linen closet, and
getting caught.  She's been known to try dumpster diving in the bathroom trash
and get stuck in it headfirst in pursuit of a Q-tip.
 

Devi also likes to cram herself where ever she can get.  I've had to
invest in bookends, and even then, I'm often startled by the crash of books as
she manages to pull them off the tightly packed shelves when executing one of
her launches.
