What is the Gray natural predator?

The question "What is the Gray's natural predator?" is a bit ambiguous. To give you a helpful answer, I need to know what "Gray" refers to.

Please clarify:

* Are you referring to a specific animal species? For example, the Gray Wolf, the Gray Whale, the Gray Squirrel, etc.

* Or are you referring to a general color?

Once you provide more information, I can tell you about the natural predators of that specific animal or species.
