Ares has two tattoos in his ears because he came from a research facility. When I first adopted him, he was skittish and didn't like to be held. I've had him for 2.5 years and he is the most loveable, silly cat I have ever met. I even taught him to sit and shake. He's my first cat and a lifelong friend.
