Yes my Madilene is solid white coat & she has one eye brown & one eye blue & she is deaf.. The normal both blue eyed & white coat cats are usally ok with Not being Deaf or blind.. Your white cats with both brown eyes are most of the time ok too.. Its just when the eyes are diff colors.. Now your cat may just have selective hearing.. You know most men have selective hearing..

[QUOTE=Jenn&Dean;2183264]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.
