That was my first thought.
All cats, domestic and their wild cousins, learn to vocalize from other cats. That's why so many people who's kitten was removed from the litter
too early all say their cat 'meows funny'. It had no teacher. This also accounts for why housecat meows vary around the country -- regional
dialects, so to speak (some researchers claim they can learn from hearing another cat on television). Wild cats (cougars, bobcat, etc) are the same.
A mountain lion call in California may sound different from a mountain lion in Montana.
Another factor is sound propagation. Remember submarine movies where the sub dives below the thermal layer in the ocean to escape sonar? Sound
partially reflects off the boundary layer between two layers of water, some passes through and distorts because of the different density. This occurs
in air as well as water. At night, temperature inversions form low lying pockets of air that are a different temperature and density from the air
above. As an animal call passes through the different layers of varying temperature and density, it distorts slightly. The stronger the inversion
the greater the distortion. This has been offered as an explanation for so many of the 'sasquatch' recordings that cannot be identified. They're
probably ordinary animals calls that went twisted.
I got all this from a grad course in forest ecology, from a researcher/lecturer whose specialty was cat sounds.
