Nettle This joyful pint-sized fluffball has an enlarged heart that beats WAY too fast. Nettle's heart is racing all the time and it's made it difficult for her to gain any weight. Our main concern is that her heart defect means she won't live very long. We're working with our Veterinarian and doing everything in our power to help Nettle's heart beat at a healthier rate and since we caught this very early, we hope to help Nettle enjoy as many days as she possibly can with her foster family. This tiny lover girl sure has made an impact already and we're sad to think that she may not live to be more than six months old
