  We present the most recent measurements of top quark pairs production and top
quark properties in proton-antiproton collisions with center-of-mass energy of
1.96 TeV using CDF II detector at the Tevatron. The combination of top pair
production cross section measurements and the direct measurement of top quark
width are reported. The test of Standard Model predictions for top quark
decaying into $b$-quarks, performed by measuring the ratio $R$ between the top
quark branching fraction to $b$-quark and the branching fraction to any type of
down quark is shown. The extraction of the CKM matrix element $|V_{tb}|$ from
the ratio $R$ is discussed. We also present the latest measurements on the
forward-backward asymmetry ($A_{FB}$) in top anti-top quark production. With
the full CDF Run II data set, the measurements are performed in top anti-top
decaying to final states that contain one or two charged leptons (electrons or
muons). In addition, we combine the results of the leptonic forward-backward
asymmetry in $t\bar t$ system between the two final states. All the results
show deviations from the next-to-leading order (NLO) standard model (SM)
calculation.
