A method for generating entangled cat states of two modes of a microwave cavity field is proposed. Entanglement results from the interaction of the field with a beam of atoms crossing the microwave resonator, giving rise to non-unitary dynamics of which the target entangled state is a fixed point. We analyse the robustness of the generated two-mode photonic 'cat state' against dephasing and losses by means of numerical simulation. This proposal is an instance of quantum reservoir engineering of photonic systems.
