Timeline at Memphis Zoo (2003-2023)

2003: Arrival in America

April 2003: Ya Ya and her companion Le Le (studbook #466) departed China for the United States, beginning their 10-year loan to Memphis Zoo. To prepare for their arrival, Memphis Zoo invested $16 million in constructing a state-of-the-art panda habitat featuring traditional Chinese architectural elements. The zoo established:

• A dedicated panda care team with experienced keepers
• 10 acres of bamboo plantations for fresh food supply
• Customized dietary provisions including panda biscuits, grapes, and sugarcane
• World-class veterinary facilities

2007: Breeding Attempt & Pregnancy

January 2007: Due to failed natural mating attempts between Ya Ya and Le Le, Memphis Zoo veterinarians performed artificial insemination on Ya Ya.

May 23, 2007: Zoo officials announced via ultrasound that Ya Ya was pregnant, generating excitement among staff and visitors.

June 13, 2007: The pregnancy ended in miscarriage. Zoo veterinarians determined the cause was low progesterone levels in Ya Ya’s system. This was a disappointment for the breeding program, but the pandas continued their public education role at the zoo.

2013: Extension of Loan Agreement

2013: As the original 10-year loan agreement concluded, Memphis Zoo and the China Association of Zoos reached a new 10-year extension, keeping Ya Ya and Le Le in Memphis through 2023.

2022-2023: Health Concerns & Return Process

December 21, 2022: Memphis Zoo officially announced plans to return Ya Ya to China, marking the end of the 20-year cooperative breeding program.

January 2023: Social media posts emerged showing Ya Ya in poor physical condition - visibly thin with sparse fur and signs of stereotypic behavior. The images raised concerns among panda enthusiasts worldwide about the care provided at Memphis Zoo.

The China Association of Zoos responded to public concern, explaining that Ya Ya was over 20 years old, which is elderly for a panda, and had chronic skin conditions that affected her coat quality. An assessment by the Association of Zoos and Aquariums (AZA) found no malnutrition or other serious medical issues beyond the seasonal fur loss related to her skin condition.
