My ball went on a stress feed strike for about a month after I got her, it scared the wits out of me. Different to hear about it or read about it in a textbook and then have it happen to you, you know? Thankfully she's okay, but there were a few days when I recall making pretty drastic negotiations with The Guy Upstairs if he'd just let my snake eat ("Dear God, I promise I'll be really really good and stop swearing and smoking and not get any more tattoos if you'll just make my python eat this mouse. Thank you.").
