My cat was killed otuside my house four days ago. I found him the next morning immediately opposite our house. I believe that he had been killed instantly, as he had no time to move away from the road. It was incredibly traumatic to find him like this, as he was a much loved and cared for member of our family. He was six and a half years old and had been living with us for just over two years. He had never seemed interested in the road otuside me property (at the end of our drive). This research has helped me understand the chances of this happening. He was just coming to an age where this was less likely to happen. We kept them in at night, but he died in winter, where he was still able to be out in the dark before I came home at 6.30pm. I would say that the road (a B road) is average traffic levels. I guess he was unlucky. We still have his brother. But I would like to eventually get a second cat, but I am obviously going to be very concerned that the same thing could happen again. The only extra thing I can do if I want them to be outdoor cats is get a light sensor cat flap that shuts them in when it gets dark. The is still a weakness with this strategy in that if the cats are out in the light and don't come in when it gets dark, then they are still otuside in the dark!We are still very devastated at our loss, as we had started to falsely assume that they were old enough to have some roadsense and keep away from the road.
