Can animals be poisoned by their own venom?

Animals will not be poisoned by their own venom.

This is because animal venom is actually a special kind of protein. For a poisonous animal, this is the tissue of its own body. If it was poisonous to itself, the venom in the body would have poisoned itself. But when such venom reaches a strange body, the body will have a serious rejection reaction, which is what we call "poisoning." So from this point of view, the cobra was bitten by another cobra, because the physical properties are close, even if there is rejection, it will not be too severe, so it is basically harmless; Cobra bites other kinds of snakes and may poison each other.
