Kate is certainly looking go to go any time now, although it COULD be another day or so! And yes, you can see her 'sunk' tailhead area from that first picture. Glad she has been a little less grumpy towards her friends!
Poor Nana goatie - dont think she will make the possible Feb dates with a tummy like that, bless her. As for your little Shimmer, I would guess pregnant - looks a bit more like a pregnant tummy rather than a lack of food tummy to me. Any idea when she might be due??
