A reaction-Cattaneo equation with fluctuating relaxation time of the diffusive flux has been explored. It has been shown that depending on the strength of fluctuations, the dynamical system exhibits new oscillatory solutions as a result of Hopf and double Hopf bifurcations leading to spatiotemporal patterns. This analysis has been applied to two model nonlinear systems.
