I recently adopted a boa that was being "power fed" when she was younger. She is actually covered in scars all over her from being kicked by live rabbits! I have her back on maintenance feeding now. I am giving her 2 large rats every 2 weeks. I worry that it's not enough, but I have been assured it is plenty. She has gained a pound since I have had her, so I guess it's Ok! May have to back her off a little more even! She is 7' 7" and 35lbs!
