Tracy, I am sorry for your loss of Sugar, but I will admit: reading this thread has been helpful for me to know what to do when the time comes...especially should it come so painfully.
I had my own pet cemetery when I lived in the country in WI, over 10 years ago; lots of squirrels from the power lines, the occasional bird from hitting the house's bay window, and prey left in the backyard. I was amazed to return to my former house & when I saw that part of the yard, it was beautiful with tall pine trees looking quite healthy.
I know that all of those animals had a major part in making that happen, as will Sugar.
