Number 1! If you picked 2 or 3, don't feel bad; at least parts of their story are plausible. I, however, have a strict policy that injuries sustained in a multi-tiered and complicated fashion are automatically suspect if they involve animals. I try not to be sucked in by smoke and mirrors, drama, weeping and wailing, and drama. Did I mention drama?
And just to put your mind at ease, no animals were harmed in the fabrication of the injuries of numbers 2 and 3.
