The time the decay occurs is roughly continuous over the hour of the
experiment. Thus the dead cat will have been dead for a random period
between 0 and 1 hours from the time it entered the box. You will find the
observed temperature of the cat will be a continuous variable correlated to
the time of the decay, and this requires an infinity of possible observers.
