As I cleaned the kitchen sink this morning, I looked out the window into the back yard and saw seven feral cats there. (The ferals here go into neighboring yards, too, so they don't actually "live" in mine.)
Earlier, I was outside removing the battery from my car (it lost its charge, I'm not sure it's dead) when a feral appeared, laid on the grass and watched me. I started talking to it. 
(I'm not actually listening to Message in a Box right now; I was listening to it earlier.)
UPDATE July 1, 2008 6:29 PM PDT:
I have since counted eight kittehs in my back yard at one time.
Recently, as I was washing dishes, a kitteh walked on the brick "barrier" that surrounds my back porch and came up to the window above the kitchen sink and sat there, watching me.
Last Tuesday morning, I heard mewing and I found an abandoned feral newborn kitten in my garage. I took it out of the garage and placed it under the back porch (because I have seen kittehs take shelter there) in the hopes that an adult feral would adopt it. On Friday morning, I found it dead.
