We perform hydrodynamic simulations of mass transfer in eccentric white dwarf neutron star binaries. By measuring non-conservative mass transfer parameters we link the results of our simulations to a long-term evolution model. We find that the binaries containing a low mass helium white dwarf evolve into ultracompact X-ray binaries, whereas the systems with higher mass white dwarfs experience unstable mass transfer leading ultimately to the shredding of the white dwarf donors potentially producing the so-called Ca-rich transients.
