It's (IT IS, see?) a really simple rule.

So in the sentence, "The snake begins to eat its tail" the meaning is not, "The snake begins to eat it is tail" so therefore the apostrophe is not necessary.

Just a tip. Of a tail maybe.

Yea, I always screw that up thinking it is to show possession, when that should be reserved for nouns and pronouns. My bad.
