However, there are a few instances where other animals may pose a threat to grizzly bears, such as:
1. Wolves: In rare cases, packs of wolves may attack and kill grizzly bear cubs or sick/injured adult bears.
2. Mountain Lions: Mountain lions may prey on young or smaller grizzly bears in certain regions.
3. Humans: Humans are the primary predators of grizzly bears, mainly through hunting, poaching, and habitat encroachment.
It's important to note that these instances are uncommon, and grizzly bears generally don't have natural predators in the wild.
