No, it's not a mountain lion, nor is it deer, elk, bear, coyote, or wolf. All are present but it's not any of them. It would be more likely to be geological or atmospheric than any of those .. and it's not them, either.
I hope this is not too harsh, I just don't know how else to say this ... this is not a search to just make the question go away, to sweep it under the mental carpet with a comforting self-lie, mine is a search for CORRECT answers. For now, the correct answer is "I don't know." That's what it will stay until I actually do know. That's what the trail cams and audio gear are for.
