Situé à Rennes (mais avec retours réguliers à Beauvais, dans l’Oise), l’Opéra des P’tites Pensées est un élevage amateur familial de rats domestiques à très petite échelle et non lucratif.
Je prône la reproduction éthique et réfléchie d’animaux qui font avant tout partie de ma famille, je tiens à ce que mes ratons soient traités comme tels chez nos adoptants. L’une des valeurs les plus mises en avant à la raterie est la transparence totale, que ce soit dans les objectifs de portées, les suivis et les problèmes présents ou les différentes méthodes.
