Jenn, I'm so sorry to hear that Ally bit you.:( I'm also glad to hear that you went to the ER. In Dec. Starr also bit me and left a couple of punture marks in my hand but I wasn't bleeding too bad and I only had minor pain. I was also put on antibiotics and it was the generic form of Augmentin which then caused me to have a stomach ache and diarrhea. I hope that you won't have these side effects.
Your bite sounds much more serious.:( I also think that some cats just get overstimulated and they don't warn you and then just end up biting. I hope you feel better soon and heal quickly. Please take care.
