Our Rattlesnake Burgers are made with USDA inspected Beef in the USA. BBQ Flavor. Rattlesnakes have a great display of camouflage. Most snakes are normally timid and secretive. When approached, they usually remain quiet to avoid detection. They may try to escape if given an opportunity. When frightened, cornered, or attacked, snakes will stand their ground and may attempt to strike at or even bite their intruder. Rattlesnakes are cold-blooded or ectothermic animals. Their body temperature is influenced more by the temperature at the grounds surface where they are lying, rather than the air temperature. High or low temperatures cause the snakes to seek escape cover or shady areas. Most snakes cannot survive exposure to direct sunlight with temperatures over 100 degrees Fahrenheit, but rattlesnakes have a greater endurance to lower or freezing temperatures.
