In Rydberg dressed ultra-cold gases, ground state atoms inherit properties ofa weakly admixed Rydberg state, such as sensitivity to long-range interactions.We show that through hyperfine-state dependent interactions, a pair of atomclouds can evolve into a spin and subsequently into a spatial Schr\"odinger'scat state: The pair, containing 20 atoms in total, is in a coherentsuperposition of two configurations, with cloud locations separated bymicrometers. The mesoscopic nature of the superposition state can be provenwith absorption imaging, while the coherence can be revealed thoughrecombination and interference of the split wave packets.
