We found a little frog in my grandmother's bathroom sink (have no idea how he got in there) but anyway, I couldn't put him outside since its December and bound to get cold. I was thinking he could wait out the winter here indoors.

I think it is a grey tree frog, but I'm not sure. Pictures to come tomorrow night. Right now he's in a tupperware bowl with a lid punched with holes. I'm about to move him to a small kritter keeper (its all I have) with some moss.

Any idea what this little frog eats. Required temps? Humidity?
