Slightly later than I'd hoped, Jenny's new, larger whelping box is ready and seems to have the "Jenny approval". Webcam has also been installed ready to go.
And Jenny is extremely large now, and feeling it. Took her to the vet for a final checkup before giving birth and all seems well. The vet did another scan and said "I'm not even going to try counting them", so it looks like a large litter is on the way, assuming all goes well, of course.
Just 7 days to go until her due date.
