This paper proposes a generalized Bell-like inequality (GBI) for multiparticle entangled Schr\"odinger cat states of arbitrary spin $s$. Based on quantum probability statistics, the GBI and violation are formulated in unified manner with help state density operator, which can be separated into local nonlocal parts. The part gives rise to inequality, while is responsible violation. not violated at all by average, except spin-$1/2$ states. If measuring outcomes restricted subspace coherent (SCS), namely, only maximum values $\ifmmode\pm\else\textpm\fi{}s$, still meaningful incomplete measurement. With SCS it proved that occur half-integer spins integer spins. Moreover, bound depends number parity particles, $1/2$ odd particle numbers 1 even numbers.
