We deal with the blowup properties of the solution to the
degenerate and singular parabolic system with nonlocal source and
homogeneous Dirichlet boundary conditions. The existence of a
unique classical nonnegative solution is established and the
sufficient conditions for the solution that exists
globally or blows up in finite time are obtained. Furthermore,
under certain conditions it is proved that the blowup set of the
solution is the whole domain.
