  We obtain generalized Raychaudhuri equations for spinning test particles
corresponding to congruences of particle's world-lines, momentum, and spin.
These are physical examples of the Raychaudhuri equation for a non-normalized
vector, unit time-like vector, and unit space-like vector. We compute and
compare the evolution of expansion-like parameters associated with these
congruences for spinning particles confined in the equatorial plane of the Kerr
space-time.
