Our cat is named "Jaune", which is French for Yellow. Yeah, he's more orange than yellow, but Jaune is such a pretty name! (Pronounced "Zyawn")
As a tiny kitten, my daughter called him Jaune Kitten. As he's aged, and gotten quite..ehem... hefty, he's now called "Jaune Great-fat-hulking-cat!"
We love every ounce of him though. =)
