The Knoxville Zoo is mourning the death of one of its black bears.
Veterinarians euthanized a 20-year-old bear named Feeber on Monday morning.
Zoo officials said the bear was often the first animal that visitors would see when they entered the zoo, and he was one of its most popular residents.
Feeber recently developed an illness that left him in severe pain and unable to walk, so the staff decided it was time to put him down.
The 550-pound bear came to the Knoxville Zoo in 1990. He was rescued by the Georgia Fish and Wildlife Service after his mother abandoned him. Feeber couldn't survive on his own in the wild, so he was brought to the Knoxville Zoo.
Expressions of sympathy for Feeber's keepers and other caregivers may be sent to Attn: Thoughts for Feeber, Knoxville Zoo, P.O. Box 6040, Knoxville, TN 37914.
