Westridge held its annual end-of-school-year event, Petridge, where students were able to bring their pets to school. Dogs competed in a talent show and obstacle course, and Lower School students set up booths with pet-related treats, toys and games to raise money for the LEWA Wildlife Conservancy and the Pasadena Humane Society. The In-N-Out Burger truck was on campus for a lunchtime treat.
