Princess Mocha Bean has always done what we call "Fanging" the Toilet Paper. She only does it if it is still in the plastic package. She does not shred it and she will not do it if it is out of the package. She doesn't eat it either.
We call it "Fanging" because that is what she does. She goes up to it and sinks her fangs in the TP as far as she can... then she leaves it alone.... very strange, and she has always done this.
