I have a dwarf hamster and he is 7 and a half mounth old. He never use to be fat. To me it looks like he has gained some weight, but are his pouches just full, because I see the extra right under where his pouches would be. I have recently change his wheel from one in his cage to an expansion pack wheel, with tubes outside his cage leading to it. Does he like his old wheel more, I see him using it sometimes. I have also been putting him in his ball for about the last week. Is it there season to store food, over the summer! Im just wondering if he is overweight!!!!
