The kitten is quite young, and looks a little sick -- watery eyes. I tried to wrangle it, the better for vet-taking, but it fled. I left it some tuna and decided to try again in the morning.
Well, I just found it again. It was under my car.
When I got down beside my car to coax it out, it climbed into the engine compartment.
The hood of my car is now up, and occasional mews emerge from the engine. I will try to coax the cat out, or failing that, take pictures of it in there.
UPDATE: Left kitten for a while, then went out to check. Kitten is not under my car, or, apparently, in my engine. Not in its other hiding spot, as far as I can tell. Probably taken inside by somebody. If it's still out and about, I expect to hear it mewing later tonight.
UPDATE 2: Spoke too soon. Honked horn; no response. Lifted hood again: saw kitten in bowels of engine compartment. No hose, of course, so I dumped most of a glass of water on it, to try to nudge it out. Now I have a wet kitten glaring at me from a point even deeper inside my engine. Attempts to take pictures have failed, mainly because there are lots of hoses and things in the way.
UPDATE 3: Operation Kitty Extraction continues poorly.
I did, however, get a picture.
To give you an idea of how deep he's in there: that is the bottom rear of the engine compartment. I had to stick my hand around the side of the engine, go in up to my elbow, scrape past a few widgets, and hope I had the angle right.
UPDATE 4/ANNOUNCEMENT: It's time for an EngineKitty LOLcat contest! Best EngineKitty LOLcat caption for the photo above wins a book from my library, to be determined. (I am thinking about H. Beam Piper's LITTLE FUZZY, which seems fitting, but I will have to check to see if I have a spare copy of that first.)
UPDATE 5/ANNOUNCEMENT: THE CAT IS OUT.
Thanks to everybody for helpful suggestions. OK, none of them worked, but the *thought* totally counts, and it wasn't like I was having any luck. The solution, if you are ever in a similar situation: wait for the cat to get bored. And annoyed with humans who keep opening the hood and poking things inside and taking its picture and asking it why it's doing this, huh? EngineKitty snuck into a convenient flowerbed between extrication attempts. I last saw it sneaking around the back of the complex, no doubt looking for something else to break into.
UPDATE 6: oh crap. I just heard a mew outside my window.
