Woodland Park Zoo's 32-year-old zebra euthanized

Woodland Park Zoo's 32-year-old zebra, Rosie, was euthanized Tuesday because arthritis in her legs caused stiffness and discomfort.

Rosie arrived at the zoo in 1977 and produced 14 foals. Her son, a 10-year-old zebra, and a 30-year-old female remain at the zoo.

Zebras may live up to 40 years in zoos.

"This condition was progressive over the last few years and treatment consisted of corrective hoof trimming at regular intervals and anti-inflammatory medications to help control the discomfort and the pain," said Darin Collins, zoo director of animal health.

"Once she stood, the discomfort and pain in her legs was quite apparent. The most humane decision was to euthanize her."

The zebras at the zoo represent the plains, or Damara species. Zebras live throughout eastern and southern Africa and inhabit open, grassy plains or well-grassed woodlands.
