Sadly, it was not to be. :( The poor creature was dead. It hadn't been dead very long, but it eyes were open and glassy, there was no breathing, and the corpse had purged itself. The twitch was apparently post-mortem.
That lead to fifteen minutes of calling the Fairfax County Not My Department, in which Animal Control, the Fairfax Police, the Herndon Police, and then the Fairfax Police again all told me to call somebody else with my pleas of "Where there are two kittens, there are probably more! Can you please send someone out here to find the rest of the litter?"
The final answer was: no, if you don't actually see live kittens playing in traffic, it's officially Not Our Problem for everybody. I pay taxes why, again?
However, the story doesn't end there. For today I was also scheduled for an "updated company photo." Why the company could possibly want a photo of me, I have no idea, but they do. And during the taking of said photo, floating near my head big and bright, the camera picked up an orb. Although I'd heard of them many times, generally associated with "haunted places," this is the first time in my life I've encountered one.
Was it actually the ghost of a poor lil' kitten who latched on to the nearest creature that showed it any compassion, lingering until it can move on? Well, no. It was a shiny dust particle. But y'know, there is a part of me that would be greatly comforted this morning if it had been.
I'm sorry I couldn't help you, little guy. :(
