Abstract
We report on the time evolution of the Wehrl entropy in a Kerr-like me dium. We show that the Wehrl entropy gives a clear signature for the f ormation of finite superpositions of coherent states (cat-like states) . In addition, the actual value of the Wehrl entropy at the time of a superposition formation gives the number of coherent components taking part in the superposition.
