Rabbits or pet rodents, particularly attention-loving or excitable ones. Although it is well known that rabbits only bite the wicked.
I like to pet the fuzzy little fingerbiters.

One who employs personal insults, shouts, or violence in the place of reasoned debate. Usually exhibited by the left, but prevalent among all political extremes.
I knew my stance was logical, but then that fingerbiter went all Barb Boxer on me. He told me not to waste his time with the facts because his mind was made up.
