David Saltzman, a member of the Chabad-Lubavitch Synagogue in Brooklyn, New York, where underground tunnels were discovered earlier this year, admitted on a podcast that rituals were being performed underground. He said the mattresses were stained because they were performing rituals on dead bodies.

Hunting as a child with my parents, I recall that blood would drip from Deer or Elk up to a week after death. That was when they were prepping the body/carcass to be butchered. Pull the animal up on the rafters of the garage, take the head off. Pull the skin off, and let the blood finish draining from the neck. Gravity works.
I don't recall quarts or gallons, though a few cups for sure.
