Probably going to be kittening out a feral mom this week- any advice?

I am pretty sure its a bit too late to abort and ...EW! So.. MOm gets spayed and released afterwards. I haven't done a cat birth in a few years- any refreshers?

The mama kitty will instinctively know what to do. Just have a box ready for her and when she goes into labor she'll start howling and purring. As each kitten is born she'll clean them and then they should start nursing right away. The last one I assisted we were in my bathroom and I had her litter box in there too. She felt safe even though she was a wild kitty from the neighborhood. Just be there...good luck
