My name is BB and I bring you Emily. Currently she is a cat. Uh, she's been a cat for a couple of years. She doesn't exactly know how to not be a cat. While her dad's side of the family are plain ole alcoholics her mom's side of the family are magically inclined alcoholics. One night her aunt decided to give Em a crash course in magic. It didn't really turn out that well.
So an underweight skin and bones mangy feral cat is going to appear on the circus grounds. Eventually she'll figure out how to turn back or someone will do something magical and accidentally trigger it in her, whatever makes the most sense in character and works at the time. In the meantime, say hello to the cat. The cat likes tuna and is insulted by cat food. Cat has also become a pretty damn good mouser, so there's that.
Please hit me up for plot and interaction! My AIM is oh deers.
PS: Obviously as a cat she can't post anything online but feel free to post LOL Cat memes in her place. If you want to, I'm using a Russian Blue cat breed for her pictures. Feel free to find pictures and say your character took a picture of her, if that is something they would do. The internet was made for cats and cooking recipes -- no lie.
