Question of The Day.

An opossum is living in my shed.
I left in the shed a bag of lawn fertilizer, in the next day the bag was open (chewed) fertilizer all over, I could see that an animal did that.
Today, early morning Greg when outside and that he was; an opossum eating the fertilizer!!!!!!
Seems like he likes the "food".

Question: Did anyone know the consequences of a fertilizer meal in an animal body?
Is he going to get bigger, hairy, or poison?
