Bs mixing and lifetime difference measurements at CDF

We review latest experimental results on the Bs mixing and lifetime difference measurements at CDF. We report on the latest beta_s and dGamma_s results from Bs->J/psi phi. We also discuss flavor specific dGamma_s measurements, including information from hadronic channels, Bs->DsDs and Bs->KK. We describe the new flavor tagging methodology and its calibration using the Bs oscillations.
