A simple qualitative model to estimate the time-scale for neutron-strange matter decay in dense stellar environment is considered. It is argued that a large mismatch between the former and the microscopic weak interaction time-scale suggests that a dual population of both types of compact objects is unlikely. Assuming the correctness of the strange matter hypothesis all of them should be strange stars. If one instead postulates accretion as the device feature for the conversion, a consideration of neutron stars structure indicates a fairly narrow range for the onset of the critical density before the corresponding Chandrasekhar mass is achieved.
