Not my hammy, took a pic at a pet store. Looks like little gremlin paws haha.

Vague title, but how does one deal with their hamster aging? I don't mean mentally, but what are some things I can do for him? He's a white dwarf hamster that I've had for over a year now, but he had an owner before me so I would assume he's around 2-ish. He doesn't run around like he used to and sort of hobbles, and seems a lot scrawnier despite being fed the same. I'm going to try and get him checked to be sure there's no issues besides old age because of his walking, but in general he just seems old. Anything I can do to make his life easier?
