The female red panda, Ta-Shi, was euthanized on Friday, Dec. 3.

“At an exam last week to try to identify the cause of recent weight loss, a large tumor was found in one of her lungs, as well as nonregenerative anemia (her body was no longer making new red blood cells),” Detroit Zoo officials said in a statement on Facebook. “After medications to make her more comfortable did not seem to help, the difficult decision to humanely euthanize her was made.”

Ta-Shi was one of the oldest red pandas living in AZA zoos.

She was a mother to nine cubs during her 13 years at the Detroit Zoo. “She is mother, grandmother, great-grandmother, and great-great-grandmother to more than 20 pandas living today in other AZA-accredited zoos,” said zoo officials.
