SIP little Riceball! I'm sorry for your loss Sakura. It's always sad to see an animal go. I couldn't watch my dog go anymore. My family and I (more my family than I) decided to euthanize him rather than make him suffer any longer. I was a big crying mess before, during, and after. He was really going in the head, though, and was super skinny since he refused to eat. He tried to fit himself into a small plant bowl. A previously 60 lb dog trying to squeeze into a small plant bowl...then walk right into a screen door. Sometimes it's just best to let the animal go. This was like, two years ago now, though. Blah. Point is, I feel your pain.
ANYWAYS. I made it a rule of thumbs not to let any small animal crawl up my bear leg ever again. My turtle did it and peed down my leg once he reached my knee. NEVER. AGAIN.
