I went to the kitchen and prepared some warm water for cleaning him. When I took him in my hand his body felt cold. After cleaning I tried to feed him small bits of cucumber, but he didn't eat any. I put a warm patch under his nest and went to work.
I came back home at lunch time and opened his cage to check his condition. When I took him his little body was still warm, but he had already left for the Hamster Heaven. He went in his sleep apparently without pain. His face was calm.
It took me some time to put him back on his nest. What I was feeling was a mix of sorrow for his death and relief because he wasn't suffering anymore.
I wanted to bury him in Mount Takao, as we did with Julita, but now in winter it's too cold to go there, so we buried him in a mini-garden in my terrace and put some flowers around him. In summer I plan to take him to Mt. Takao.
He had a long and happy life. He was a wonderful hamster. He will not be forgotten.
