I put "yes, very smart" only because she is smarter and has more personality than people expect from a cute little bunny. She's not rocket scientist, but she is very good at figuring things out, differentiates completely between Paul and I (when he tries to play toreador with her, she just stares at him like he's insane, wheras she and I MUST play almost every morning) and between children and adults, and is just "no dumb bunny."
Of the dogs my family has had in my lifetime, Sheba, the Shepherd mix that was my first dog and best friend, was the smartest dog I have ever encountered, bar none. Freckles and Bruni, the St. Bernards, were kinda smart when they wanted to be, but pretty much big lovable doofuses, and Gracie, the Great Dane mix, was very sweet. (But really dumb, but it wasn't her fault.)
