I'm learning more by reading this thread, had no idea I could feed dog food to these breeders! Now, that goes for both mice AND rats?

I have Purina Dog Chow for our dog, who also gets table scraps every so often.

But, I bought this bag of Rabbit, Gerbil and Other Small Animals with alfalfa hay but it seems like mice just ground it up and make a dust pile out of it, the rats won't even touch it so they've been stickin' to scraps?
