do they sell old hamsters at petstores [specifically petsmart]? cuz i sorta just noticed this and it seems like my hamster is a bit old.. their seems to be a bit of hair loss on his head and on his sides, but i could be from fleas.. [ive seen him itching himself like the way dogs do when they have fleas] and he seems to be a little slow..my dad has also noticed this too..so my main question is do they sell old hamsters at petstores?
