We describe the implementation of neutrino emissions in the general-relativistic code Whisky by means of a simplified leakage scheme. We discuss the problems and solutions encountered during the implementation of generic hot and nuclear equations of state. We present a series of tests and consider in particular the impact of neutrino cooling on the stability of non-rotating neutron stars with finite temperature. We find that for stable models close to the maximum mass, collapse to a black hole can be induced by cooling at the stellar surface.
