They were unlikely friends, a grizzly bear cub and a wolf pup. But the pair shared a friendship that lasted beyond their days tumbling around the gift shop at the Woodland Zoo as youngsters.
Six years after the video was shot, Lil' Bear and Tala still remain close, according to footage posted by Dennis Crossland, an employee at the former Pennsylvania zoo.
The clip features some photos of the rambunctious duo all grown up and seemingly posing for the camera. The "aww"-inducing footage has already garnered more than 200,000 since it was posted on Jan. 27.
Bella the dog and Tarra the elephant were another pair of unlikely friends whose tender interactions captured the hearts of workers at the Elephant Sanctuary in Tennessee. Tarra mourned Bella's untimely death and carried the dog's body to the spot they often spent time together.
Although the video above might make you squeal, there has been recent controversy regarding the purchase and ownership of exotic animals.
In October, Terry Thompson released a slew of exotic animals, including Bengal tigers and a spotted leopard, from his Zanesville, Ohio, farm before committing suicide. Officials were forced to kill at least 48 of the animals.
The incident highlighted the importance of enforcing exotic animal laws, particularly in Ohio.
Grizzlies like Lil' Bear can grow to be about 6 feet tall and run at speeds of up to 30 miles per hour, National Geographic explains.
The bears are extremely powerful and potentially deadly, but their population is threatened in the United States due to poaching and loss of habitat, according to the World Wildlife Fund.
