In 1995, a tiny stray kitten somehow got into the enclosure of a 560-pound grizzly bear named Griz at a wildlife rehabilitation center in Oregon, and because apparently kittens are born with absolutely no concept of reasonable risk assessment, he walked straight up to the bear while Griz was eating. The people watching were pretty sure they were about to witness the shortest friendship in history.
Instead, Griz reached into his food, pulled out a piece of chicken, put it down next to his paw, and let the kitten eat it. And that was basically it. The kitten, who was given the incredibly creative name Cat, apparently decided he lived with a grizzly now.
They started eating together, sleeping together and playing together, and Cat would even run up and smack Griz on the nose, while the 560-pound bear somehow understood that his roommate was approximately the size of one of his feet and reportedly backed off when their play got too rough.
Apparently bears are eligible for the cat distribution system.
