When I got Paddy, she was just a bitty little thing, now, she must be reaching full adult size. Gray tree frogs grow 1-2 inches big, and she's most definitely close to 2 inches. One of the other Grays I got is growing incredibly fast also (the other 2 seem to be a little slower, one is a male for sure though) I just can't believe I've only had my baby for a month and she's pretty much a grown up now She started with small crickets and is chomping med/large ones down no problem now.
