My female BP is 15 mo's old and she's probably near 37-40 inches long ( her last shed that I was able to measure was in May, and it was 35 inches long), and I weighed her two days ago and she's 695g. My males quite a bit smaller than she is, probably only 2 1/2 feet long, and weighs around 400g right now. He'll be a year in sept. I feed them both rat hoppers every 5-7 days. Usually 5 because they start roaming by the 4th day. My female has only refused a meal once, and my male is the 'garbage disposal' of the family.
