catch only suppresses errors, catchQuiet suppress errors and warnings. But I don't think you can extract the message from them?
I haven't tested this but the only way that I can think of getting hold of a warning message is through altering the GUI logger and log handler that maya uses to output to the script editor. The MayaGuiLogHandler class in maya.utils passes messages to OpenMaya.MGlobal.displayError/Warning/Info for different types of logs. As a way to get more control over how exceptions are handled (like having exceptions that are raised in your scripts send you an email), you can also customize error outputs in Maya by overriding maya.utils._guiExceptHook.
