I have a female het piedball she is a late 09 around 200grams. She does not like me at all hisses every time I try to get her out, but she also does the strike but not eat thing with frozen mice or rats. Toss in a live mouse she stalks it for a while and eventually strikes and eats. Its frustrating though I wish she would eat frozen. Once I have her out she is chill but until you get her in hand she is in attack mode.
