We obtain the lower bounds $m_WDM > 3.2\,keV$ and $m_FDM > 5.210^-21\,eV$ on the warm dark matter and fuzzy dark matter particle mass, respectively. When dark matter is coupled to a dark radiation bath, we find that kinetic decoupling must take place at temperatures higher than $T_kd > 0.7\,keV$. We also discuss future prospects of stellar stream observations.
