Abstract
We consider a quantum superposition of Bose-Einstein condensates in two immiscible internal states. A decoherence rate for the Schroedinger cat is calculated. An experimental scenario is outlined where the decoherence rate due to the thermal cloud is dramatically reduced thanks to a "symmetrization" of the environment which allows for Schroedinger cats to be approximate pointer states.
