The fate of electric dipoles inside a Fermi sea is an old issue, yet poorly explored. Sr1-xCaxTiO3 hosts a robust but dilute ferroelectricity in a narrow (0.0018 = n* (x), resistivity follows a T-square behavior together with slight upturns (in both Ca-free and Ca-substituted samples). The latter are reminiscent of Kondo effect and most probably due to oxygen vacancies
