Miaow! Feed me now, dammit!
You know it, I know it, cats love to exploit gulible humans. Now researchers are theorizing that our modern moggies are the best sounding decendents of miaowing wild cats.
Humans respond most to pleasant miaows as opposed to horrible yowls and reward nice sounding felines with food and preferential treatment. Some scientists think this has lead to supercats, vocally best prepared to mooch food and shelter. Others think cats are just damn good at learning what to do to get free chow from us and learn their miaows independantly.
