all my BP's are offered food every 4 days, right now they are all on mice, will be doing the rat switch fight real soon, order being made. 3 of the 6 will take 2 mice a offering, 1 will just keep eating what i throw in there. (god i love her, but 4 mice at a offering is just insane for a late 2011), the other 3 are hit or miss at this time. sometimes it is 1 a week to 1 every other week. switching to rats would be far more cheaper in the long run then feeding multiple mice each feeding.
