Yeah, I heard that from BHB. But my two black pastels are total sweethearts. My cinny pewter was a heavy-duty biter for the first 6 months, but she's made a complete turn-around and is another sweetheart.
My axanthic, on the other hand... she's gone from being completely neurotic to biting to pooping on me to simply hissing every time I touch her. At least she's improving?
