I will not lie or try to BS you on my previous post. I do not remember where This information came from but probably on KS burmese forums. Let me explain a little more. I used to keep large snakes almost exclusively and as anyone that has kept Burmese Pythons for any amount of time it is well known that they are extremely susceptible to RI's. I use to spend a lot of time on the forums over there and thi stopic always came up and after discussing this information with many well experienced keepers this was the information that was passed on. I do not want to guide you in the wrong direction but I am pretty sure that Rob Carmichael as well as Happy Hillbilly (his KS username) will tell you the same thing. The cracking of the lungs is why it is suggested to raise the temps a bit when a RI is suscpected. To help keep the lungs moist and to help promote the healing of them. Hope this explains my original response a bit. Todd
