Technically adopted him from the streets but this is Binky. Whenever he vocalizes he makes a point of staring directly into my eyes, he will then tense his entire body as if his screams demand the eldritch gods come into our plane of existence by using his body as the gateway.
Imagine getting a cat from an animal shelter and deciding to pick the very sweet and gentle one who hasn't made a single sound the whole time you're there, and being told "yeah she doesn't meow like other cats do", and then when you say "oh it's ok, I don't mind a cat who isn't very vocal!" the shelter's people look at you like they're about to say something but decide against it.
And then you bring your kitty home and the first time she wants your attention, she opens her mouth and the sound that comes out is a low, soothing but abnormally long continuous tune that you can only describe as something between mongolian throat singing and a didgeridoo.
