Tiger Euthanized At Louisville Zoo

POSTED: 3:03 pm EDT March 17, 2008

Louisville, Ky. (WHAS11) – Boris, a 17-year-old Amur tiger, died at the Louisville Zoo Sunday, March 16. Seventeen is considered to be geriatric for big cats.

After staff observed Boris having a seizure on March 5, they kept a close eye on him. When he had another seizure a couple of days later, Zoo veterinary staff did a complete medical work up. Even though a cause of the seizures could not be determined, Boris was given medication to try to control them. But it didn’t work.

“Our medical evaluation suggested the cause of the seizures was most likely in his brain,” Louisville Zoo Veterinarian Dr. Roy Burns said.

On Sunday Boris wasn’t doing well and began to have more seizures despite treatment.

“His prognosis was not good,” Burns said. “The medication to control the seizures was not working, and he was also showing signs of spinal disease suggested by weakness and instability in his rear legs.”

Zoo staff then made the decision to humanely euthanize Boris.

“We miss him terribly,” said Dave Hodge, a keeper who cared for Boris, “but we knew it was time to let him go.”

Staff members who worked closely with Boris surrounded him as he passed away. There wasn’t a dry eye in the room.

“I had my hand on his chest as I said my final goodbye,” Hodge said. “I will really miss him.”

Boris weighed more than 400 pounds in his prime, and although he was every bit a wild animal, staff described working with him as easy.

“Boris was really personable,” Hodge said. “Even though he was big and tough, he really enjoyed greeting visitors when they came to see him at his exhibit. He was definitely a special cat.”

BORIS INFORMATION
