Rabbits can be trained to do things and distiguish humans from each other. It might be coincidence that last night when I asked Bunny to give her ball to dad and she did but I like to believe that bunnies are smarter than we give them credit for.
They thump their feet in the wild to let the other rabbits of the warren know they sense danger and in time so they can all retreat into the dens unscathed.
But it is a little dumb that even after 6 and half years, Acacia still gets nervous when I pick her up or if Matt tries to pick her up. :)
