I had my girl on one every 5 days but they might be too small. If you don't already, get a scale, weigh her and get back to us on what she weighs. There are a few ways to tell what size food your BP should be taking as well. One is you should feed prey that is about 1.5 times as wide as the widest point of your snake's body. The other is that you feed prey that weighs 10-15% of what your snake weighs.
