It was not your fault that you expected them to tell you where they might be holding your cat when you showed up and asked them about it--it was entirely their fault for hiding the ball! What a bunch of sadistic paper-pushers those people are! I don't care how busy they may be--they obviously didn't make the slightest effort to help. There's just no excuse for that.

I'm so very sorry that you had to suffer the loss of your sweet Kuhio. I hope you and your new kitty have many very happy years together.
