Poor snakes
The only time BPs should be housed together is when you are *intentionally* trying to breed them. BPs are extremely solitary animals; housing them together causes unnecessary stress. "Cuddling" is merely them fighting for the best hides, basking spots, etc.
After proper QT, a group photo shoot is fine, but extended or permanent housing together is asking for trouble.
Please give these wonderful animals the respect they deserve and provide them with their OWN enclosure.
