We introduce the "Binomial Schr\"odinger Cat'', formed by a quantum superposition of two orthogonal generalized binomial states of electromagnetic field with maximum number of photons N. In particular, using resonant atom-cavity interactions, we propose a non-conditional scheme to generate a two-photon (N=2) binomial Schr\"{o}dinger cat in a single-mode high-Q cavity. We also give two single-shot schemes to detect the generated ``cat'' state, by exploiting suitable probe atoms that distinguish the two components and reveal the coherence of the superposition. We finally discuss the implementation of the proposed schemes.
