Well, it has been 5 days, so you can. What size meal do you give your ball? I give my 10 month olds a mature mouse about every 5-7 days, unless they refuse. So the main question is, how large of a meal do they get? If there actively searching the enclosure I would feed again. Some BP's this time of year like to put on some weight before it gets to cold. (That's my person experience with them in IL)
