I'm a little late as well in my condolences, but know I know your pain too. I had to have my 14.5 yo Smokey put to sleep 2 years ago and it broke my heart. I was with him till the end and surprisingly it was quite peaceful. We have him buried in the back yard with a cat statue that actually looks like a grave marker that I finally found on Halloween (he was a black cat). I don't have photos handy, but I do go out to sit with him every now and again. Of course we hear/see/feel him around quite often. He used to jump on the bed and we can still tell when he comes around.
