It is a sad day for me I lost the very first RES I got almost 30 years ago, when I was eight. I was always proud to say that I had my RES for almost thirty years, I am almost 100% positive it was old age, because she was already an adult when I got her. I am sad to see her go, but I take comfort in knowing I had her for a long time, and she had a pretty good life, eating and basking in the sun.
