Cat Pregnancy Calculator

This calculator turns a cat mating date into a kitten due date using the published feline average of 65 days. Enter that date and it returns the expected day, the usual 63 to 67 day window, the recorded 58 to 72 day extremes, and the dates for pinking up, palpation, an ultrasound, an x-ray and the queening box. A second action works backwards from a due date you want, and a third says how far along she is on any given day. A queen still carrying at day 70 is overdue and needs a vet, so the window matters more than the single date.
