Ah, the subtlety of rabbit language.
Though rabbits don't bark noisily or make other such vocal sounds, if you are patient enough to observe them, you will understand what they are trying to tell you. It is sad that people sometimes treat rabbits like they are exhibits in the cage, without caring to communicate with them.
I went over to pet Whitty, but she surprised me by hoping away, out of the reach of my hand. Then I noticed that she was looking at me ever slightly. She is actually waiting for me to play "catch" with her.
And so I went forward and she happily allowed me to scratch her neck.
