I say two weeks but it could be any number as long as it's consistent in timing. I don't weight mine hardly at all. Young ones every few to several months. Big ones every year or so. My big Blood hasn't been weighed in years because of her size. It's nice to do it to see progress but I wouldn't do it all that often and worry about it without reason.

Yes I don't think he's underweight. He looks very healthy and plump but not fat.
Even so I thought that under 150 grams would be extremely little for a BP of almost 6 month. That's why I became worried.
