You may suspect the beating of a dead horse by now, but the problem is actually that the animals in question are still alive. As was discussed, the alive cats expect to see something when the box opens.
If we interact with the Schrödinger cat superposition state inside the otherwise isolated box so that we will only have dead cats result, what do the alive cats see? There must be a place into which those cats can jump. However, it cannot be the room where the experimenter observes them, since the experimenter only observes dead cats after having applied the ‘rotation’.
