Jan 12th the frogs weights were 4.4 g and 21.9 g. I re-weighed them today to see how they were doing and they were 5.7 g and 25.2 g respectively. I wonder how much of that was from food and how much was re-hydrating (both looked in good health on the 12th). All weigh ins are done after a feeding.

And now to answer the question that everyone wonders about but is afraid to ask- "How much can a frog pee in one sitting?".

My scale has a little removable pan on top of it, so when I'm done weighing the frog I just put the pan in their cage and let them get off it on their own time. On the way back from the weighing, the fat one peed all over my arm. Still in the dry pan (she managed to get it all on me), this was my golden opportunity to reweigh her and finally answer the above burning question that's been nagging me since I was old enough to think about the urinary output of various creatures (probably about the same time I saw an elephant at the zoo cause a tightly localized torrential downpour). She was now 23.7g. That's 1.5g, or almost 6% of her body weight! My own, now grossly inadequate, personal record is closer to 0.6%, thanks for asking.
