Yayyyyy, I have never been so happy to be wrong! Took out a box with a little hay to drop Belle's kits into as I counted them today, and she really DID have six, and the little runt is still alive (and looks fed, as in smooth skin, just smaller). Belle seemed a little upset when she saw me lifting the empty nest, I don't think she saw me put them in the box, but she didn't get stroppy, just set to tidying up the nest when I put them back.
ANDDDD, Spot had her litter sometime between feedings today, and she had SEVEN!!! Since no one got dropped on the concrete or stepped on this time (her first surprise litter, it's a wonder she still trusts me), I am hoping they all survive.
Quartz is due in 3-5 days, so stay tuned!
