I have doubts about the common belived rule that you should feed your snake pray that is as wide around as they are. I have had my BP for a year and a half now and he is basically full grown and has alot of girth to him. However, he still has a very thin neck, like as wide as my finger. I just fed him a rat that was as wide around as he is (basically adult size) and I was fearful that his neck would rupture. I don't want to feed him like that again and think smaller would be much better. Plus hes been off feed for a month and a half, the last meal was the same size. So am I being paranoid? Am I right? What size should I be feeding an adult (pictures please!)
