Please keep your indoor cat's indoors at all times or have a safe area.  Our little Sydney was killed by our neighbors dog that was out loose and came over to our property and pinned her to our house and malled her. She suffered for fifteen minutes before she died from her wounds.  It was the most difficult thing I have ever witnessed and having to say goodbye to my baby while she took her last breath in my arms.  Not one day goes by that I don't think about her.  This has changed my life in such a dramatic way that I know my future will be lived with great meaning.
