Wayne. our Meow Meow "lost" his voice for a time.
It became just a weak, small, scratchy sound.
After a few months most of it is back, but not nearly like it was before. more "croaky" if you know what I mean... not smooth like before..
But it never seemed to bother him.. even now he does (what we call) silent meows when we are close and can see him.. you can see his mouth move and almost can read his lips.. but nothing comes out.
But at 4 am he'll be at the foot of my bed and everyone can hear him bellow.. FEED ME! LOL..
