What a coincidence to see this thread -- I also have an eight-month-old Syrian that I've started wondering if I've been giving her too many high-fat treats (nuts, sunflower seeds, dried mealworms) and whether she's getting heavy. I just weighed her tonight and she's 185 g. (A couple months ago she was more like 155 g.) She looks a little chunky to me these days, but it's my first hamster and I'm just not sure. I'm attaching (hopefully successfully) a picture of her and would also welcome input. Good luck on your hamster, Pranjyboy, and thanks for the suggestions, m&m.
