Here's the situation: I was at Petco and in passing the food isle, I saw the brand I usually buy for my mice for a good price and grabbed it. The next day, I was looking at the bag and realized that it was hamster and gerbil food instead of mouse and rat food. The store is pretty far away, so I'd rather not try to return it. A lot of the food in the mix looks like the same things in the mouse food (various seeds and stuff). I know that it's not the same as the mouse diet, but if I mixed it with the mouse food I have, will it be okay to feed it to them just to use up that one bag? I have almost a whole bag of mouse food, so it would be about a 50/50 mix.
