Milwaukee County Zoo rhino 'Mimi' passes away

MILWAUKEE (CBS 58) -- The Milwaukee County Zoo is mourning the loss of one of their beloved animals. 

The Zoo said goodbye to rhino, "Mimi," last week. 

Mimi was estimated to be 34 years old. Her care team was monitoring her quality of life closely, the Zoo said, because she'd had health issues typical of an elderly rhino.

Mimi's lead Zookeeper, Ray, described her as a star pupil for training, saying she “flirted” for scratches and treats.

"Mimi was playful right until the end," the Zoo said in a Facebook post. 

May she rest in peace.
