How come venom (from spiders or otherwise) affects the victim, but not the predator once the prey is eaten?

Answer 1

Generally most types of venom have to be directly injected into your bloodstream or tissues, or in some cases the eyes or other sensitive areas intended for it in the case of animals like the spitting cobra

The walls of your digestive tract are anything but sensitive, and usually anything that doesn’t get degraded by acids and enzymes simply passes through without harm or absorption.
