When one of Jon’s nephews came to visit, he became convinced that we had a talking cat. I talk to Jack all the time, and he talks back. He understands when I am calling him, when I say “dinner!” and when jon wants to play with him. We understand when he is hungry and when he is playing with his toys (he has a special gargle-esque meow for that). But, unlike this video suggests, I do not generally meow or growl at him.
Also of note: I have never ever seen Jack’s tail do the thing it’s supposed to do when he’s angry. I think he just doesn’t get mad.
Bruce has a specific meow for right when he’s about to puke, it’s so funny!
