According to Quantum FFF Theory, there is no dual Cat problem based on the idea that two or more instant entangled anti-symmetric copy particles living inside different copy universes solves the dead or living cat problem. Probability philosophy based on a Charge Parity and Time (clock) symmetric copy raspberry multiverse, says that symmetry between both (anti) cats is always conserved. If The symmetric anti Cats in the anti universes are dead and in our material universes the cats are also dead.. ( 8 or 12 symmetric universe is till unclear.)
This means, that the cat in the box is dead or alive even before one is looking, because he probability is 50% by the decay of the radioactive atom in the box, which is entangled with its anti copy particles far away in one of the other universes inside the raspberry multiverse. see:
Er=epr in the Super symmetric Cyclic Multiverse and in the Lab Without Strange Cats. https://vixra.org/pdf/1604.0229v2.pdf
So I postulate that ALL POSSIBLE ALTERNATE HISTORIES of OUR MULTIVERSE
exist because there is instant mirror symmetrical wavefunction collapse in at least two distant
(Charge and Parity) mirror symmetric universes.
