Are lycans and vampires real

Sure if you are a Bahhtt! ( Bat) there are Vampire Bats that drink blood as part of their food chain! There is also an animal called a Zorilla ( lit. Little Fox) that is something of a Vampiric Fox or Skunk-like creature. Noted Travel author Gunther ( who was not, alas, a zoologist type), did make reference to this creature in one of his Inside books. Among human beings an actual appetite ( more accurately, thirst) for blood can happen, but is four star Wacko abnormal. Do not confuse with legitimate medical use of Blood transfusions.
