I was out in the front yard when i looked to my coop and saw a big chestnut colored cat was walking around the perimeter of my coop. 2 1/2 - 3 feet from head to tail. it does not look like a bob cat because it has no spots. i saw it later on in the evening and shot at it (missed on purpose) i got scared but came back around 8. What type of cat is thi and how do i stop it without killing it?
