Can a horse on Howrse foal a day late?
If you take care of the horse on the day that it has to give
birth, but you don't pay for the birthing, the mare will lose the
foal and you will lose a karma point.
If you do not take care of the horse, it will not age and
therefore will not lose the foal until you take care of it. If you
do not have enough money for the birthing, you can just leave the
horse alone until you raise enough money.
