The nganga is kept in a domestic sanctum, the "munanso", typically formed in a cellar or a shed in the practitioner's backyard. When an individual practices both Palo and Santería, they typically keep the spirit vessels of the respective traditions separate, in different rooms. The nganga is "fed" with blood from sacrificed male animals; this is poured into the cauldron. Species used for that purpose include dogs, pigs, goats, and cockerels. This helps to maintain the nganga's power and vitality and ensures ongoing reciprocity with the practitioner.
