We live in between two large farms and have a coyote problem in this area.
I couldn't stand worrying about our six cats being outside anymore...are they coming back from the barn, did a coyote get one if they were late coming back to the house, did one get into the farmers mower.
So, we decided to keep them inside the house. But...we built them an outside play area. A cat door was put in the basement window where they can go out to this play area.
