We study anisotropic cosmology in Horava's gravity theory and obtain Kasner-type solutions, valid for any number, d, of spatial dimensions. The corresponding exponents satisfy two relations, one involving the marginal coupling {lambda}. Also, Horava's (super)renormalizable theory predicts (super)stiff matter whose equation of state is p=w{rho}, with w{>=}1. We discuss briefly the implications of these results for the nature of cosmological collapse.
