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