The past two days at around 5:30am, a stray Tom cat has climbed onto my front porch and come right up to our bedroom window. My male indoor cat freaks, jumping and swatting at the Tom. He runs away when I go outside, but returns the next day. I live in the city and don't think that catching and releasing him would be a viable solution. How can we get rid of this guy so we can get some sleep and my cat can get some peace?
