I recently got a hamster about 2 weeks ago and at first he was eating but he was v picky and was hoarding his food and super active the first week . I sleep late so sometimes I would see him But after I cleaned his cage he stopped running on his wheel and eating and was always sleeping. and at night he jus wakes up to the sand bath and stuff for like 3 mins and then go back I thought maybe he would be up and eat and everything when I was asleep but I took pictures of his food and it seems like he doesn't eat any ... any advice on what I should do ? I feed him sunburst & I tried giving him food / treats he takes it but doesn't actually eat it and puts it down ...
