I was just trying to give them a varied diet, not too much of one thing. Just looking in the fridge for whatever we won't eat (not spoiled), we often have some berries as well like strawberries, blueberries and raspberries. How about cheese and bread? I clean up their food bowls and give new food every day or every other day. Today they seemed very content, I've never seen rats so happy LOL. I'm pretty sure I have four males and three females in the bunch so I'm guessing I'll have to separate them at some point?
