Meet Jack. He's a cat who would be a tenor bass if he sang in a choir.
Due to a type of laryngeal paralysis, which is when an animal's wind pipe's airways don't work properly, he has an unusually deep meow. Yes, that's a cat, not an adult human.
Turn up the volume and check out Jack's special meow below.
Brace yourself the next time you call, "Here, kitty, kitty," to this one.
