[LunaTheHamster1]

I only know mostly about syrians, and obviously not knowing what his life was like before he was abandoned but normally as a hamster gets older you can tell by their fur. For example when they are younger it looks more glossy/shiny/sleek and I know as Luna has got older it just doesn't look as shiny, it looks more ruffled, a little bit of an unkept look. Does that help at all, maybe someone else on here knows a bit more about ageing hamsters? I know it's a tough decision but t does sound like you only have 2 options, 1.) do nothing and see if it gets worse or 2.) put him under and see if they can help him.

Just know that whatever you choose to do and whatever happens you have been spoiling him and given him a lovely home. I am sure he couldn't ask for more than that.
