That looks painful!! Ouch! Ally, you really need to chill out! I wish I could give some ideas as to why she is so dern agressive. I know sometimes kitties can get too rough and may break skin but this looks really serious. Sigh, some cats are mean, just like some people. Hopefully little Ally will grow out of this meaness. If you don't mind my asking, what was Ally/you doing just before the attack? A look at the situation surrounding it might be helpful.

I hope you heal quickly!
