The nonequilibrium statistical operator method is used to obtain a system of kinetic equations describing the dynamics of parametric spin waves in an arbitrary inhomogeneous case. The spectrum of homogeneous collective oscillations of a packet of parametric waves around isotropic and anisotropic stationary states is found from these equations. Criteria of stability for individual modes of the collective oscillations are obtained.
