I'm involved in rabbit rescue and have 7 at home. Once in a while if I'm taking them to the vet I'll bring them to work with me in carriers. Coworkers come from all around to fuss over them, and the rabbits love it. They're closely supervised and used to being handled.

One day during an important meeting the CIO picked Earl out of his carrier, a tiny 2-pound grey netherland dwarf who knows he's cute and rides it for all it's worth. She spent the whole meeting with him in her lap -- Earl probably thought we were all there for him.
