Meaning & Story
A classic name of possibly Greek origin, associated with harvest or summer, honoring Saint Teresa of Ávila.
Theresa is a name with centuries of history and genuine depth — associated most powerfully with Saint Teresa of Ávila, the 16th-century mystic and reformer, and more recently with Saint Teresa of Calcutta. As a pet name, it carries an unexpected warmth: there is something tender about giving such a historically significant human name to a beloved animal, a kind of elevation that acknowledges how much they mean to you. Pets named Theresa tend to be steady, generous presences — quietly essential to the household's well-being.
