My niece has been fussing over momcat - who was very bony - like a Mother Hen, feeding her only the best, and lots of it. One kitten didn't make it, and momma has only 4 working nipples but that seems to be okay with her 4 little fatties.
She even has her own room with a view and a custom-made kitty nursery/condo.
Sorry for all the pics! Just does my heart good, in these awful times, to see this poor tiny girl safe, happy, and content with her babies.
