Actually when irl blood feeders (such as vampire bats) feed, they need to constantly keep pissing while sucking blood, so as not to burst from the volume of liquid they’re feeding off of.
Because blood is relatively nutrition poor. Just mostly water with an irony taste. (Uh… I wouldn’t know personally ofc. Uhm, a friend told me. A human friend, as all we humans have.)
Surely, they must take in fluids besides blood, right? Otherwise they’d shrivel up!
