As always in this hobby, " To many questions, to many opinions not based on fact and what do we do. " As you said, Mark; " Pay attention to what your snake is telling you. " It cannot speak, but actions are much louder than words. If it spends to much time on the hot spot, it is probably to low of a gradient. If it is always on the cool spot, it could be to warm. I like to see these animals do what alot of people have seemingly forgotten that they do naturaly " THERMOREGULATE. " Consistency in temperature is the worst thing in the world for boids " this is especially true with aboreals " and even so with terrestrial boids. They have humdreds of temperatures to choose from at all times. Aboreals are subject to air temperatures and terrestrial boids are developed to take SURFACE temperatures wich vary GREATLY. In the shadow of a leaf, the temperature can be 20 degrees cooler than six inches over and out of the shadow. The ambient temperature in the jungle at any time could be in the 90s, but that does not mean that all the boids are sitting in the 90s! Take your RAYTEK gun out on a ninety degree day and start taking surface temperatures of everything and you will be amazed at what you will find as far as varying temperature. I still believe that there are to many of us trying to to be experts and look smart, I still think that common sense is greater than intelligence. How many baby boas " especially " do you guys think are found in the wild basking on a rock in direct sunlight? Probably SLIM to NONE. Another thing to take into consideration is prey. I believe most neonates in the wild eat amphibians probably more than small mammals. Mice do not occur naturally in South America and are different than rats. I have seen babies puke mice and not puke rats? Sometimes, I think that regurgitation can even be natural; " What is a small snake with a big meal going to do if it gets startled? Regurge, so it can get away faster. " Commonsense applied to proper husbandry will avail many truths. Or we can base everything we know on outdated books that were written by people that still cannot base their writings on ROCK SOLID scientific evidence..........Tootles........Johnson Herp
