The North Carolina Zoo is mourning the death of a beloved 12-year-old cougar.


ASHEBORO, N.C. (WTVD) -- The North Carolina Zoo is mourning the loss of Heath, a 12-year-old cougar who died Friday after a decline in health.
Heath arrived at the zoo in 2014 with his sisters, Olive and Willow, after the three were orphaned in the wild in Oregon. While Willow later moved to another facility, Heath and Olive remained at the zoo.
As he aged, Heath developed chronic kidney disease and mobility issues that affected his quality of life. Zoo veterinarians and animal care staff made the decision to humanely euthanize him.
"Heath was an outgoing cougar and a fan favorite," one keeper said in a statement. "My favorite part of the day was being loudly greeted with chirps, purrs and meows."
Keepers said Heath enjoyed shredding boxes, chewing on bones and taking naps. He was also known for a unique habit of blowing bubbles by dunking his head in water while straddling a ball.
Another keeper described Heath as a "special cat" with a memorable personality, saying they loved his "grumpy old man" expression.
Zoo officials said Heath will be greatly missed by staff and visitors alike.
Animal care and veterinary teams are closely monitoring Olive and providing extra care and enrichment as she adjusts to life without her brother.
