The kitten, Mimi, was at the Vet friday getting an xray. Ends up she broke her pelvis. The Vet said she most likely fell. Probably while chasing around with the other cats. So, luckily no surgery, just need to keep her confined for a couple weeks. She seems to be in a little pain, but not too bad.
The Mama Cat, Pretty, is holding her own. Friday night, she spontaniously aborted one of the kittens. All was fine after this happened. She's been eating normally and being loving. I was told when I got her that no one had heard her meow for the 3 weeks they had her. She was meowing at me Saturday morning, perhaps to tell me what had happened. She will go into the Vet in the next few days to make sure all is well with the other kittens, which are due to be born this weekend if all goes according to schedule.
