I am so very sorry to hear that Oscar went to the bridge, I am sitting here crying for you as I write this. All I can offer in comfort is that he said goodbye to you before he left even though you didn't know it at the time. I am sorry that you didn't get to bury him as you wished, but only his body died, his spirit lives on. He will be waiting at the bridge for you, someday you will see him again. Try to comfort your other cat as much as you are able. Hugs and a prayer for you that you can find peace.
