My 11 year old seven pound female eats halfpounders (large rats) in the summer (weekly) occasional jumbo (pounder) and mediums (~150 grammers) year round. She gets food offered weekly but it varies from year to year month to month if she feeds consistantly. In my opinion i would offer all bps weekly prey items in the warm months. If you want to go every other week or longer save that for when the temps drop. Happy herping.
