Assemble this circuit on a mounting board: USB power + roller switch + wire + cloud. The roller switch should be closest to the edge your pet will access, and the USB power should be farthest to keep her from tampering with it. Secure the wire bit by wrapping it around the USB wire and tucking it between littleBits feet and the mounting board. Bunnies love to bite loose wires!
Mount to cage, hide power wire
Tie the mounting board to cage with wire twist ties. Bunny tried to nibble on these, but I told her "Bunny! No wires!" Then she settled on rubbing her chin on them.
Extend roller switch
Glue or tape a short segment of a drinking straw to the bar where your bunny comes and goes. This is also like a drive through window where she can beg for treats. Insert the end of a chop stick into the drinking straw.
Fold a small rubber band over a bar in the cage and slot the other end of the chop stick through the two ends of the rubber band so that the chop stick is hanging as much as a centimeter above your lever switch.
Train bunny with treats
Cadburry was already using this "beg bar" to specifically ask for Kale, but I am sure you could train any bunny to beg for a specific item if you reward her for her efforts. They really listen to your voice, so also reward verbally and with pets when you give them their favorite treat. Soon enough, your bunny will have it mastered.

I used IF littleBits THEN email (see pictures). I named my cloud bit "Cadburry", so the emails she sent me had the subject line "Cadburry is begging"; the emails read something like this, "At June 21, 2014 at 05:01PM, Cadburry requested Kale."
Another recipe I used: IF littleBits THEN Google Calendar. Now I have a nifty visual calendar to show the times she tends to ask for Kale. It's usually when we open the fridge or come home.
Cadburry sent us about 80 emails over the course of five days, which my Yahoo email at first put into the junk folder. I then set my inbox to place them into a special folder.
