  We introduce a concept of squeezing in collective qutrit systems through a
geometrical picture connected to the deformation of the isotropic fluctuations
of su(3) operators when evaluated in a coherent state. This kind of squeezing
can be generated by Hamiltonians non-linear in the generators of su(3) algebra.
A simple model of such a non-linear evolution is analyzed in terms of
semiclassical evolution of the SU(3) Wigner function.
