Dear everyone: It can never be possessive of anything. Love, me.

Yes. If you write the word

it’s

it had better be a contraction of it is.

It cannot possess. You might say, “Its chew toy was a stinking mess.” Never would you say, “It’s chew toy was a stinking mess.”

Thank me later. First, go into your novels and do a ctrl-h and replace all the it’s with its, UNLESS it’s a contraction. Check each one. Universal copy and replace is going to make you sad.
