Weighing them before they've passed their rats is kind of cheating. Empty weights (right after pooping, but before a meal) are a much better indicator of actual weight gain. 200 grams in a month is impressive (and definitely not unheard of), but I could weigh some of my animals right after feeding day and claim a 200 gram overnight weight gain!
