My cat is an indoor-only cat and I read somewhere that they are
natural hunters, preferring to sleep during the day and hunt at night.

       I do notice that my cat is more active at night, and usually if I go
into another room and come back out she is hiding.  I usually know where
she's at, and she sees my eyes, but she always lunges at me (claws not
extended) as I walk past.  Sometimes she doesn't touch me, sometimes she
touches me with her front paws (just to prove she can).

       Does anyone else's cats do this?
