  This paper studies inflation and isotropization in the quintom model in the
Bianchi I, Bianchi III, and Kantowski-Sachs backgrounds. First, we investigate
inherent properties and generalize Heusler's proposition. Then by the use of
the dynamical system approach, we consider the system in multiplicative and
collective modes of potentials. The conclusions of Collins and Hawking and also
Burd and Barrow are discussed.
