We got ours nearly two months ago. Ur story seems really similar to ours. I think that its also the change in environment for them and they need to get used to it. We've slowly added more branches etc for the frogs to explore and they love it now. The bigger one was posin on a leaf the other nite whilst I tried to get some decent pictures lol. They're slowly 'comin out of their shells'. They're not bothered by ours cats either which is cool. I'm glad u saw urs eatin. That's brilliant news!
