Kittens are doing well. They even held still for a claw trim Wednesday afternoon, which makes tickle time rather less painful (and helps save the furniture).
We finally trapped Momcat! She's gone from thrashing around in the trap to sulking in the trap. The kittens are avoiding that area; seems they've gone from being afraid of the two-legs to being afraid of their own mother. Once the various vet offices open, it'll be time to make a feral cat spay appointment.
Momcat photo to follow, at some point. She's a big gray shaggy thing. Come to think of it, I think she's been in my kitchen at least once before; one day, during the summer, Something came in through the open back door and was stealing Piggy's food; it was either a big shaggy gray cat or an enormous shaggy gray squirrel.
Update 1: come the morning, Joy called a nearby vet and made an appointment, then loaded the trap into the car. Oopsie! Somehow, the cat escaped. Now my car is infested with big fierce feral cat. And a re-set, baited trap, just in case she gets hungry sometime soon.
Update 2: evening, and the varmint's still hiding under the seat. She'd dang well better get back in that trap by morning! Also, she's stinking up the car something fierce.
Update 3: early in the night, someone turned on the hazard blinkers. Joy went back out and turned them off. Then, later in the night, someone tripped the trap. And ate the food contained therein. And didn't stick around: Momcat was back to lurking under the seat.
So, after some calling around, we decided to perform a Barricade-In-Place and drive to the vet's office. This was uneventful, but the vet techs, upon surveying the situation, didn't figure they'd have enough room to work in, in the little Prius.
At the moment, the car's back in my driveway with the doors open, and Joy's trying to coax Momcat out from under the seat and out of the car, so the car can be cleaned out and returned to service, and we'll try the trapping operation again in a few days, maybe with a newer trap.
Also, no photo of Momcat. She just wouldn't hold still for one... and I don't really feel like sticking a camera down under the seat and trying random flash photography.
Pawnote: the kittens are no longer sufficiently worried about Piggy to stay out of my office. During the night, they were wandering back here, despite Piggy being on guard.
