Oh no, poor little kitty....
You did the right thing, Kirsten, I would have done the same! If that cat had a home, it's humans will go out looking for him/her. Of course, it won't be a happy reunion for them, but at least they will know that they don't have to search any further... .
I would go back to this place regularly, and if the body is still there in two days, then I would take it with me and bury it. It would be to sad to leave it there forever.

Poor little cat, be happy now at the Rainbow Bridge !!

Thanks Kirsten for caring for this poor little thing
