Thank you for the reply Numpty, it was helpful.

I just did some additional looking at chorus frogs. I think the fact that mine is so juvenile is really hindering me finding a proper ID. Based on SOME photos I'm finding, I keep waffling back and forth between Cope's Gray, Spotted Chorus, and Spring Peeper (though the geographic range is WAY off for the Peeper). None are perfect matches, and at that, only some of the photos look similar.

I suppose I'll just keep feeding and growing him/her, and nail down an ID as it grows.

EDIT: Oh, and thank you for the photo compliments.

Thanks and regards,
