Query: Large Splitting Massive Schr\"odinger Kittens   Probing quantum mechanics, quantum aspects of general relativity along with
the sensing and the constraining of classical gravity can all be enabled by
unprecedented spatial sizes of superpositions of massive objects. In this
paper, we show that there is a feasible setup sourced by realizable magnetic
field gradients ${\cal O}(10-100)$ Tm$^{-1}$ to construct a large spatial
superposition of ${\cal O}(10^{-4}-10^{-8})$ m for masses ${\cal
O}(10^{-16}-10^{-14})$ kg over a time period of up to $0.1-10$ seconds.
