How long can a Vampire survive without blood
Survival of the fittest, or oldest?
The question is how long can a Vampire survive without blood?
It varies from vampire to vampire. Generally older vampires can go longer periods of time not having to feed on blood; if we look at younger vamps they must “feed” more often than the elders. Why? Older Vamps are conditioned to longer periods of dehydration until they get their normal food supply, this conditioning comes with age. A younger vampire generally lives day to day trying to quench the thirst that a newly turned vamp has acquired. If they do not get this supply of blood in most circumstances they will be immobilized from the lack of the essential food.
Lets say for example you were able to catch a vampire. You took that vampire and put him/her in a area where they could essentially be starved – How long would it take to starve a Vamp? Results vary depending on if the vampire is young or old, and by young I am referring to the amount of time he/she has been a vampire. The older vampires can generally go for longer periods of time without having the need for the blood, and as I mentioned before they do not die of lack of blood but become immobilized (This will also be covered later).
The rule for the amount of blood Vampire needs is that for every year that you are a Vampire is one day you can go without feeding. So, if you are a Vamp that has only been turned for five years then you can go five years without blood; if you have forty years of being a Vampire than you have forty days you can go without feeding, and so on… One day of being a Vampire is equal to one year you can go without having to drink/eat.
So that Vampire we put in confinement will “survive” the amount of days they have of being Vampire.This is the reason why newly turned Vampires must feed the first day they are infected, and this is why the thirst is so strong. The longer you are a vamp the longer you can hold out without blood and the easier cravings become, keeping in mind there are aways some exceptions.
