It's really depends on individual animal.. size of that animal size of prey and "schools of Feeding".
As of now I have only 2 BP's 1050g Female .. She Eats 55-60g rat every week now but she just wake up from long fast so I deliberately feed her smaller meals upgrading her up every 2 weeks...
She gonna finish up on 80-90g rat every week.. because i plan breed her in fall...
My 1200g male get 60-70g rat every two weeks...
Yes I know that some of You will say that is not enough.. but he looks good and he progressively gaining weight from 808g in April 2010 till 1200g weighted empty 2 days ago.. so i dont see reason to feed him more often..
I probably will bump him to every 10 days feeding schedule at the end of summer before breeding season to let him store little bit more energy.
With babies before I was feeding: up to 350g is every 5 days, 350-700 every 7days.. after that females stay on every 7 days schedule males goes on every 10 days ... after male reach 1000g i switch it to every 14 day schedule bumping it to every 10 before "breeding season"
But as i said.... that's my way and everyone have different opinion on that subject.
Edit: I feed live so a notch smaller prey in my case give me more mental comfort
