Snakes continue to grow throughout their lifetime, so the burm will grow no matter what...however, feeding him that often could easily result in obesity. When I worked in a store with large pythons like Burmese, we tended to give them one meal every two to three months depending on the size and activity level of the snake. Albeit, one meal might mean two rabbits for a long slender snake as opposed to one pig for a large stocky snake, but still. 0.o Am I making sense? I'm tired...
