I fed my 18 months male BCI a live jumbo rat(411 grams) 2 weeks ago. He pooped it out three days ago and two days ago in two batches. So his stomach was empty. And this is the time when he usually gets hungry. I feed him on average every 2 weeks a large live rat(300 grams). Today i brought him another Jumbo live rat(370 grams). I opened his enclosure and let him smell the rat first as i usually do. I know from his reaction whether he is hungry or not, whether he wants to eat or not. He did not react in anyway and showed no signs that he is interested in food. So i did not give him the rat. The reason for that obviously is that the rat he ate last time was bigger than usual. So his body did not require more food now. So he knows if his body requires food or not. This is not about overfeeding, its about that false claim that boas will eat as much as you give them and that they will never refuse a meal, that they can,t judge for themselves if their bodies require food or not
