Thanks for the hope guys! I played some croaking noises with no success, except for the other frog singing along. I put 3 more plates of water out, and all of the cats are locked down stairs now, so I'm hoping he's upstairs. I looked all over the room but couldn't find him. If I don't find him in the morning upstairs or in any water dishes I'll focus on downstairs more. I'm hoping the cats didn't find him. :\ I also patched the screen.
