Our Bunny is deaf also. The loud meow was how the vet figured she was deaf when she was just a little kitten. We were fostering her mom from a no kill shelter when she and her siblings were born. White hair and blue eyes, the combo for deafness. She is almost 4 years old and we love her, she is such a character. She knows 2 hand signals, wagging finger means "no" and hand waving towards us means "come here". That is about it for communication.
@RayFerd61 Gracie is also white and blue-eyed. (Actually one eye is green, but she's deaf in both ears.)
She knows "get down" (point at floor) and "pretty" (the ASL sign), which I'm pretty sure she thinks is her name. I have the same sign for "no," but she pretends she doesn't understand it, haha.
