I am so very sorry that you lost your beautiful Sammy at such a young age but that is the reality of the world we live in today. In developed countries, dogs are not left to run the streets unsupervised and neither should cats. The main danger is cars - and it absolutely breaks me down to tears every time I see a cat lying dead in the street and I have to say that I am extremely angry at whoever put them in that danger. We have to make the decision to keep them safe, not just fed and loved. There are also predators out there, of the animal and human kind. Please people, keep your cats indoors or if you are going to let them enjoy the outdoors, please always be there to supervise (not leave them alone on a balcony, even on a rope, or on a rope on a fenced in yard). This is the care they need and deserve and it will be less heartache for everyone. It's not always a drivers fault when they hit a cat - they are so small and hard to see, especially at night.
