See an Adorable Polar Bear Cub Dream as It Slumbers at an Ohio Zoo

A sleeping polar bear cub at an Ohio zoo was caught apparently dreaming and the zoo got the adorable slumber on video.

In the video, the cub is seen cuddling a stuffed animal, stretching out her paws and sticking out her tongue as she switches between sleeping belly-up, belly-down and on her side. She can also be heard making a noise, which “is a sound of contentment, much like the purring of a cat,” Columbus Zoo and Aquarium spokeswoman Jennifer Wilson told ABC News today.

The 5-week-old cub was born at the Columbus Zoo in Powell Nov. 6 to a polar bear named Aurora and was under her mother’s care in the den until the staff decided to raise the cub themselves, Wilson said.

POLAR BEAR CUB UPDATE: At 5 weeks old, the polar bear cub is doing very well; she weighs a little over 4 pounds and…

“Nearly a week after the cub’s birth, Aurora began to take breaks from caring for the cub,” Wilson said. “When these breaks continued and became more and more frequent, the Zoo’s Animal Care staff made the decision to remove the cub from the den and began to hand-rear the newborn.”

The cub, who weighs in at just over 4 pounds and does not yet have a name, began to open her eyes Friday and “so far, she is doing well,” Wilson said. “She is very much still a newborn and eats and sleeps a lot.”

The newborn cub joins three other polar bears — her mother Aurora, Aurora’s female twin Anana and a male named Nanuq — at the Columbus Zoo’s Polar Frontier, where there is a freshwater pool, dig pits, smell ports and deadfall trees for enrichment, Wilson said.

Wilson added that polar bear populations are declining because of the disappearance of sea ice and that experts estimate there are only 20,000 to 25,000 polar bears left in the wild.

“Zoos play an important role in education and conservation and our hope is to conserve this species for generations to come,” she said.

Glacier the polar bear dies at Point Defiance Zoo

The first polar bear believed to be treated with chemotherapy in the United States died Wednesday at Point Defiance Zoo & Aquarium from liver cancer, officials said Friday.

Glacier, 19, was diagnosed in February with advanced liver cancer, which spread to his lungs and abdominal lymph nodes. He also suffered from heart disease.

“Our entire zoo family is saddened by the loss of Glacier,” said Karen Goodrowe Beck, the zoo’s general curator. “He was a magnificent ambassador for his species, helping hundreds of thousands of zoo visitors to connect with polar bears and learn more about the perils they face in the wild.”

Glacier was one of three polar bears at Point Defiance. He came to Tacoma in 1997 with another bear, Blizzard, after the two were orphaned in Manitoba, Canada.

Boris, 29, also lives at the zoo in the Arctic Tundra area.

A routine exam in February uncovered Glacier’s mass and heart murmur.

Veterinarians worked most of the year with specialists in cardiology, radiology, oncology and surgery to devise a unique treatment plan for the polar bear’s cancer.

Oral and intravenous chemotherapy started in April with the help of Dr. Lisa Parshley from Olympia Veterinary Cancer Center.

“Glacier was extremely sick from two very bad diseases when we first diagnosed him,” zoo veterinarian Karen Wolf said. “He was not moving well, he was sleeping more, he wasn’t interacting with zookeepers and he was uncomfortable.”

She said the treatment improved his quality of life for the last eight months and allowed him to eat more, wander near the stream in his exhibit, participate in his training and swim in his saltwater pool.

A necropsy was performed Thursday. He died of complications from a large liver tumor, according to Point Defiance Zoo.

The record of his treatment likely will help with the future treatment of polar bears, and possibly other bears, Wolf said.

Glacier, who was 9 feet tall and weighed about 950 pounds, was not a geriatric bear. Life expectancy for a male polar bear in the wild is 20 years, according to the Association of Zoos & Aquariums.
