I've noticed he goes to his food bowl more often, I could have perfect timing but it is a bit of a concern for me. I haven't replenished his food for 2 days now because his cheeks are almost always full when I see him. I did give him a small boredom breaker with food in it just in case he is bored; I see him lying around in weird places instead of inside his houses, is that normal? I might do a spot cleaning later today if he has dirty spots around his cage. His cage is pretty big, not like anything you buy from pet stores, so I don't think this has anything to do with the amount of space he has.

I'm not sure what to do and I could use some tips from people who have had hamsters before, preferably Russian dwarf hamsters but any tips are welcome.

Update: Remi sadly passed away overnight, he lived a long good life. I will miss him.
