Over feeding a snake that's already at a perfect weight can cause the snake to be over weight and get stretch marks. This isn't good for the snake, only unless you are trying to make it gain weight if it was under weight. 6 meals within 5 days is definitely not good. You should give the snake time to digest all of the meals before feeding it another. I think you should at least wait a week or two before feeding it again. Feed the snake only once a week, which is highly recommended for snakes since they have slow digestive systems.
