[Underworld] So William and Marcus were bitten by wolves and bats that made them the first vamp/werewolf ,but in their era were they never bitten by any other animal like a dog? a cat? horse ? rabbit?

 Their farther was never bitten by anything???? if they had would they be weredogs and were rabbits? and why didn't Marcus turn into a werebat creature instead of a vampire ?

Their bloodline is rather magical. Being bitten by animals may have been a metaphor rather than actual fact. But assuming it's fact it's likely the animals that bit them were also magical to some extent. Or at least aligned magically in some way. Bats beings of the night and wolves beings of the hunt. As for Marcus he did turn into a werebat rather than a vampire. It's just centuries of repression and evolution have created the lycans and vampires. Marcus rejected his bestial nature and retained his human appearance after some time. William embraced the beast and became it. But both were considerably more monstrous in appearance and ability than their later descendants.
