At Como Park Zoo & Conservatory in St. Paul, Minnesota, all eyes are on two polar bears that zookeepers hope will soon breed, helping safeguard their species. Astra, a 5-year-old female, and Kulu, a 6-year-old male, were introduced after genetic research showed they would be a good match. The bears enjoy playing, eating and “snuggling” together, senior keeper Allison Jungheim told The Minnesota Daily, and if they do successfully breed, their cubs will delight visitors and serve as “ambassadors” for their “wild counterparts.”
