Hey Johnny, They definitely have a meow type sound they can give out.
100 times... well... Bigger? Deeper? Larger air Volume? Throat volume? Hard to explain.
I've heard several vocalizations, both at the farm with the captive cats, and in the field, that AFTERwards I would have had to call them a 'meow' sound, but when I heard them, that's not what popped into my head!
Possibly the best way I can describe it is... The housecats try to do it, but they're too small! The Cougars do what the housecats are trying to do. Effortlessly. They can do it soft and quiet, but it's still big and still carries. No "Y" sound to it, but the rest of the 'meow' is there. More like a moan. "MuhRoooo" in the upper register, quiet, smooth, with maybe a little gravel on the end.
Bobcats have a varied vocabulary too. Often more nasty than the lions, but they definitely have more sounds than just the nasty growl.
Possible.
