Whenever I am alone I often find myself acting like a cat. Most of the time when I get the urge to act like a cat, I will just get on my hands and feet and start to walk around rubbing my head on corners. However, sometimes when the urge is strong enough, I will open a can of tuna, put it on the ground, lie on my stomach, and start eating it. I'm a 22 year old man by the way, if that helps. Is it normal if I have an imagination this big?
