@patiodog,
Thanks patiodog.
The form said first trimester.
I asked the kid if she'd heard anything and she said that the vet said something along the lines of yep, pregnant, nothing we can do, sorry, she's gonna have babies... We'll find out conclusively on Monday I guess.
Do they ever just tie tubes? (Kid may well have misheard or be engaging in wishful thinking -- while she knows there are too many cats she's generally pro-kitten.)
The other thing is that the form indicated that she is pregnant, present tense, with some instructions of what to do because of that (wish I still had the form, it's been passed on).
The good news is that the person lined up to the adopt the cat went ahead and adopted it even with the possibility of kittens.
All I know for sure -- both the "spay" box and the "pregnant" box were checked, as well as the "first trimester" box.
As for the other ones being knocked up, yeah. My friend said hopefully "maybe they're all males!" but I pointed out that there are a few calicos and calicos are always female (right?) We're redoubling attempts to capture, really not going very well so far. But we're going to keep trying.
