OK, so that little kitten turned out to be a horror show. This little bunny looks friendly, though, and it needs someone to hold it and pet it.

Attach (Ex) A vampire bunny has a +4 racial bonus on grapple checks.
Create Spawn (Ex) A vampire bunny can only create spawn from other rabbits it has killed with its blood drain. The victim rises from death as a vampire bunny in 1d4 days. This undead rabbit is under the command of the vampire bunny that created it, and remains enslaved until its master's destruction. A vampire bunny may have no more enslaved spawn than its Charisma modifier; any spawn it creates that would exceed this limit become free-willed undead. A vampire bunny may free an enslaved spawn in order to enslave a new spawn, but once freed, it cannot be enslaved again.
Incisive Bite (Ex) A vampire bunny adds its Dexterity modifier to its damage rolls rather than its Strength modifier.
Occasionally, when a vampire recalls its former life, it remembers its fondness toward a pet it owned when it was a flesh and blood creature. While the vampire does not actually experience that feeling of fondness, the warped nostalgia drives it to create an undead mockery of its pet. Oddly, rabbits seem to be the only animals that spawn into vampires, while other animals merely die when subjected to the vampire's blood drain. Like many rabbits, these vampire rabbits escape their masters and wreak havoc on the surrounding land. Only instead of destroying crops, these rabbits destroy livestock and turn animals against their masters. Vampire bunnies can also spread their vampirism to other rabbits, with the potential to create a nightmarish situation in regions overrun by rabbits.
