You'd be amazed at what they can eat! Good rule of thumb is to use a prey item that is about as big around as the largest part of your BP. As a reference, my male is only slightly smaller than Penny (love her name BTW!) and eats large adult mice. The benefits being that you can go a little longer between feedings, you only have to feed one prey item as opposed to 2 or 3 at one time and appropriately-sized prey aids in proper jaw developement.

But I certainly wouldn't waste what ya got! Next feeding, I'd give her a fuzzy, let her finish, then see if she wants a second. That should help you gage a little better what she can handle in one feeding!
