Tilly the rat died sometime during yesterday afternoon/evening, while I was at work.
When I got home that evening I had a quick look in the cage and I saw that she was lying in front of her nest box.
When I went to play with her later on during the night she was still in the same spot, and was cold.
I don’t really feel all that sad for her, as she was probably in some form of discomfort, and she was old.
Wherever she is now, she is at rest
