Help, my cat talks!

My name is Mirella, Mirella Manush. I am almost ten years old, I have grown a strange tooth, and I just found out that I am a vampire! Now, when the sun sets behind the horizon, I can turn into a bat, and my cat turned out to be my totem protector. But the coolest part: I have started to understand the language of animals! Isn't that crazy? It will be great to help my dad treat animals in our zoo! But for now — shhh! — I must keep everything a secret from him, as my mom and my beloved aunt Ellie asked. And that's the hardest thing in the world!
