That is so funny, but only because it reminds me of some silly habit of mine, which by the way has nothing to do with voice training (my voice is fine for the most part, done been through all that practicing long ago to get it right) or really anything in particular. But I meow all the time, just randomly, I meow and mew along with songs and music, kind of a variation of humming. What's even more silly is here I have a dog as a pet, yet make cat noises all the time. I dunno why I do it, just one of my odd habits, I just pick up strange habits out of the blue, overdo them for a while til one day I pick up a new one and start fresh again with that. But here you sound so sophisticated and intellectual (must be the accent), then pull out a cat and start meowing, so totally unexpectly adorable.
