My gray tree frog, Willow, is a voracious eater, she loves food. I have been limiting her at 2-3 small crickets a day, but am still feeding her daily as she is a juvenile yet. Paddy and Silvermist both eat the same amount, they are bigger than her, but not fat looking like Willow is. How do I tell if she is overweight? What do I do about it? She is definitely the laziest of all my frogs, but I wonder if that's just because she's getting fat. I don't believe it is bloating, though I did at first, she's been like this since I got her a month ago, and she eats and poops like all the others.

Silvermist is on the Right, Willow is on the Left
