Barky is sick, which is kind of not cool, as she's never been sick before and I don't know how to help her. Try as we might we can't think of why she would be so poorly :(  She threw up a load of food (is it the food? Something she ate? Something she ate and got stuck?) and is now shivering in her corner, all cold and passive :( Won't eat. Won't fall for my teasing. I hate this, as I am entirely powerless and can't find anything to blame.
