Propagation of (3+1)D short light bullets in media with Kerr-like saturable nonlinearity is considered. The influence of higher-order terms - third order dispersion, nonlinear dispersion and self frequency shift are taken into account. A trial function corresponding to the product of (2+1)D gaussian beam and approximate solution of (1+1)D generalized nonlinear Schrodinger equation is applied. The Euler-Lagrange equations for varying temporal and spatial widths of the bullet are obtained. A stationary corresponding to small higher-order terms of these equations is found. The influence of material nonlinear coefficients for the stationary widths is discussed. The linearized form of Euler-Lagrange equations is obtained. The periods of oscillations of temporal and spatial width are found.
