My 4 y/o male orange and white is a wonderful cat overall. He does not go outdores and has all his shots and has been nudered. Lately, when he sees another cat outside (which I cannot identify as male or female) and I scare him by accident, he flips out on me and kicks my butt- scratching me and acting like Cujo! It sounds funny, but it is to the point where my wife has left tonight with my mother to stay with her; fearing for her legs, etc! He's my best friend. What can I do??
