RattyRat's Review: You will want to stay away from "seed mixes" or other "mixed" rat food diets that contain a variety of different bits of seeds and food items to choose from. Although these forms of diets seem like a good choice, they are known to be less nutritious. The other major problem with these diets is that a lot of rats won't eat all the different bits of food contained in the diet, picking only the tastiest items to eat. Granted you could watch the bowl and not fill it again until they eat every last bit, but your still not sure if they are all eating everything they should. One rat could be eating all the sunflower seeds, while another rat is eating all the dried fruit, while another rat is eating all the kibble, etc... With "mixed" diets it is simply impossible to guarantee a balanced diet. This particular diet also contains ethoxyquin and BHT which are preservatives known to be toxic.
