Meow Cats vs. Rrreow Cats

Over the years we've been fortunate enough to have had a number of cats, all of which vocalized differently.  Some were big talkers, others had puny voices.  Now our oldest cat (at 17) is stone deaf and vocalizes extremely loudly, like a human wearing earphones and exaggeratedly talking too loud.

But over the years the cats seemed to segregate themselves into 2 types of talkers: the meowers and the rrreowers.  It's a distinct difference between the initial "M" sound as opposed to the initial "R" sound.

There is no sound in the following photos, but Tizzy is a Meower.

Sammy (the deaf one), on the other hand paw is a Rrreower.

And that's all they have to say about that.
