Exactly. The prey species has to have a viable population to keep the predator fed. And the predator has to poop the remains of the prey. In the case of snakes they also regurgitate pellets of hair and bone the same way owls and raptors do.
I don’t want a terrarium that never gets cleaned over my head with only drywall in between.
“they also regurgitate pellets of hair and bone the same way owls and raptors do”
No they don’t.
The closest thing to that is some egg eating snakes, who use specialized muscles in their throats to crush eggs, and spit out the shells.
“In the case of snakes they also regurgitate pellets of hair and bone the same way owls and raptors do.”
A healthy snake does not regurgitate hair and bone. It passes through their digestive system. The general exception to this are egg eaters that will regurgitate the shell of an egg.
