I don't usually venture onto Rainbow Bridge but when I saw the thread title I had to.
Little Nell had an amazing life with you. I had no idea hamsters could be so tame. I've never had a close bond with any of mine as with a house full of cats letting them out was a logistical nightmare, unless I put them in the shower to run around (with the water off obviously).
I hope she went peacefully to the Bridge as elderly hammies tend to do.
Run free little one. xxxxxx
