Nobody knows how was the life of Marnie in her first nine years of life, but when they found her on the streets of a small town in Connecticut in 2012 it was obvious that she had a desperate need of care and love; no one was looking for her, so they took her to a shelter . Fortunately after 4 months a woman adopted her in New York and gave her a fantastic second chance.
