Boomer, one of the Houston Zoo’s two elderly grizzly bears, was humanely euthanized today after a long life. The decision was made by the bear’s keepers and veterinary team after the nearly 40-year-old bear began to become uninterested in food, less active, and less responsive to his pain medications. After reviewing all options, our veterinary and bear experts decided that the most humane option was to peacefully euthanize him.
The geriatric bear came to the zoo with another grizzly bear, Bailey, in 2007 from the Houston SPCA where they had lived for a year after the organization confiscated them from a private individual who was not taking good care of them. The pair had lived in tiny cages and were found to be in very poor health, with severe dental disease, and obesity from lack of exercise. Since moving to the Houston Zoo, Boomer underwent extensive dental care including five root canals and seven tooth extractions performed by veterinary dental specialist Dr. Bob Boyd. Boomer was diagnosed with lymphoma in both eyes in 2010 by a veterinary ophthalmologist Dr. Nick Millichamp and underwent oral chemotherapy later that year. His right eye was removed 2012 when it became ulcerated and painful. The lymphoma in the left eye caused complete blindness but Boomer was able to navigate his enclosure well. In recent years, Boomer began receiving treatment for chronic arthritis and a non-resolving infection that unfortunately had become debilitating, regardless of medication and care. Boomer was beloved by the zoo staff, who have fond memories of his love for his pool.
Whenever an animal dies, no matter what the reason, it is a tragic event and our staff morns the loss of a member of their family. The health and wellness of our animals is a great priority to our team and with four incredible veterinarians and a complete veterinary clinic and world-class animal keepers, our animals receive the best care possible. While it’s always exciting to celebrate births at the zoo, we also mourn heavily when one of our animals dies.
