I'm putting together a feeding chart for feed sizes vs BP weight (for a pet, not a breeder.) I know the standard is to feed 10-15% of your BP's weight, about once a week, but I know at a certain point they don't need that much. I've seen the feeding chart that floats around here, but it doesn't seem to follow a percentage guideline. When would you typically switch to a 'smaller' prey size? (I've heard 7-10% at some point?)
