My mom has a long haired white cat with one blue eye and one brown eye, and he is deaf. He leads a normal/good life. He has had a few issues with balance on occasion, but other than that, he's just fine.

And he's not even afraid of the vacuum! Haha

Although, when I go home for an extended stay like a holiday where I cannot leave Dean at home, my cat terrorizes him, chasing and sneaking up on him and he doesn't know what's coming.

He has a blood curdling meow... But we love that about him too.
