I've seen (without a doubt confirmed) mountain lions in the wild on two occasions. One was pretty close, but I was in a short tower blind. They're silent when moving, in my experience. You don't get much more than a flash or blur out of the corner of your eye. I was able to get a pretty good look at the one when when I was in the blind though, as he/she slid between cactus patches. There are plenty of them in South and West Texas. There have been more times when I could have seen one, but wasn't sure. When I said they were silent earlier, I meant they're silent when I've seen them. Camping in South Texas I've heard them at night, unseen, but mighty close. Thier scream is like nothing I've ever heard. It's nothing like the roars on movies or TV. It sounds like a women in absolute terror. Shrill and peircing! I can't think of anything else it might sound like. It would send a chill down the spine of the bravest man. We slept with revolvers in our bags. Between big cats, coyotes, and "economic refugees", I'm suprised we slept at all. Take care.
I remember one time in particular when I was just a wee lad and a bunch of us got together and went camping for the weekend. This was poor people camping out so everyone slept out under the stars.
I don't know what the reasoning was but everyone spread their quilts, blankets, and such in a long line instead of everyone having a separate spot, maybe it was for protection.
What I recall so vividly was that when we got up that first morning there was a very large cat print in the soft dirt not very far from the edge where I had been sleeping! That was the last night I got too sleep on the outside of pallet because of my mother's insistence...
Over the course of years I've had enough meetings in similar ways, seeing one off in the distance, hearing one, "cough" way to close for comfort, tracks, and the like for me to not recognize their sign. And the helluvit is there are several different places all around the USA where the, State Wildlife, Fish and Game, or however the agency is worded or called claim there are absolutely no mountain lion, puma, panther, or whatever they're called in your bailiwick and you know absolutely different.
It may not prove the Powers That Be know the truth and either aren't Or can't say what they themselves know to be true but one thing you can do is say, "Well the next time I see the big cat close enough to get a sure shot I'll kill it and you can come get it to prove whether they're here or not."
The next thing you'll probably hear is, "Oh No! You can't shoot them without a tag or some other form of permit."
When I sent the story to one of our daughters who does live in the country a little further out she wrote me back saying, "You know dad, no matter how many times you hear one of them scream it sends chills all up and down your back?"
And that it does.
