Not sure if anyone asked you but how often do you think Volturi feed? I know vampires don’t need much in quantity..
Edward mentions that his family and him feed about every two weeks. Now, I assume that the “vegetarian” lifestyle has to have some drawbacks with one of them being the need to feed more often. Going off of this, I would guess that a “carnivorous” vampire would need to feed about every month.Â
Now, the Volturi have an ..interesting dynamic with their Uber Eats Heidi bringing their meals to their chambers, especially given the large number of vampires that live within the castle. Besides the 5 coven members, there are 10 permanent guards and 17 unnamed guards. That means there are a total of 32 vampires within their castle…which is a lot of vampires to worry about feeding.
Since there is such a large number of vampires within the Volturi, they probably break the feedings into two group. Normally, the two groups would probably be the Coven (5) + permanent guard (10) and the transitory guard (17). Heidi’s tours are bimonthly, and it keeps everyone on a schedule for their feedings. I’d imagine keeping everyone on this sort of schedule would help with slip-ups too. However considering that the Volturi employee a large number of “gifted,” there are probably instances where a vampire is permitted to feed twice a month if they over-exerted their gift. Additionally, I would assume Guards are allowed to feed the “traditional” way when they are out on missions, as long as they are outside of the Volterra city and properly dispose of the body.
