Cadbury the rabbit isn't up-to-date on social media, but she can now send email. Instructables member JackANDJude built an electronic trigger that sends an email whenever Cadbury presses the lever.
She used a CloudBit controller, a roller switch, and a chopstick. It's placed on the outside of the cage to protect the wiring from rabbit teeth (bunnies love to chew on wires).
