It so happens that cats " do not go " ?

I had 2 pet striped, most ordinary pooch, a car hit when he was 1.5, the second die is not clear from what is now picked up a small kitten in the street (good people thrown on the market in a frost-month cat).She is now a year, I experience that with her anything can happen, because all the animals died in the same vozraste.Samoe interesting is that if they told me, "do not go" why I find them in such circumstances, that simply can not bypass, because they will die without me in the street! not looking and not looking after specifically, but to save from destruction! How to stop this misery? and true belief that one color goes and gets along and the other not?
