Max size rat that should be fed to a BP

[Egapal]

I don't think stated that they were feeding a rat that size every 7 days. It was suggested to use 150gram rat every 7 days instead of one 300gram rat every 14days

I was not commenting on the OP or anyone else's feeding schedule. I was merely stating that the 10% to 15% of the snakes weight every week does not necessarily apply to adults. The OP asked about the max rat size and I think what they might be referring to is the fact that you should not keep up with the 10% to 15% once a week rule into adulthood.
