Main article: Quantum mechanic
Main article: Housecat

Schroedinger's cat is a unique special monster that is only generated in the possession of a Quantum mechanic. Quantum mechanics have a chance to be generated with a large box and Schroedinger's cat will always be generated INSIDE the first Quantum mechanic to be generated with the box. No further mechanics will be generated with the box or Schroedinger's cat. It is the only monster that is generated in a container.

When you open the large box, there is a 50% chance that Schroedinger's cat is alive, otherwise it is dead. A message to this effect is displayed. If Schoedinger's cat is alive it is immediately placed in an adjacent square to the large box, and it may be hostile. If it is dead, a "housecat corpse named Schoedinger's cat" is placed in the large box.

If Schroedinger's cat is dead, you can reanimate it using turn undead.

Schroedinger's cat is otherwise identical to a housecat.

Messages

The housecat inside the box is dead!
Schroedinger's cat is dead - a housecat corpse is in the large box.

Encyclopaedia entry

Imagine a sealed container, so perfectly constructed that no
physical influence can pass either inwards or outwards across its
walls. Imagine that inside the container is a cat, and also a
device that can be triggered by some quantum event. If that event
takes place, then the device smashes a phial containing cyanide and
the cat is killed. If the event does not take place, the cat lives
on. In Schroedinger's original version, the quantum event was the
decay of a radioactive atom. ... To the outside observer, the cat
is indeed in a linear combination of being alive and dead, and only
when the container is finally opened would the cat's state vector
collapse into one or the other. On the other hand, to a (suitably
protected) observer inside the container, the cat's state-vector
would have collapsed much earlier, and the outside observer's
linear combination has no relevance.
