In interpretations without natural factorizations, the cat won't just be dead or alive. It won't even be a cat. So let's say the cat is isolated in a box totally shielded from any decoherence from any environment.. and the any factorization between system and environment inside the box is suppressed.. what would become of the cat? just a blob or without any form? Would it's brain still work even if it's not a classical brain but totally composed of wave function without any factorization? How can you imagine, visualize or think of dynamics of wave functions without factorization and without any collapse?
