Dean was back last night!!! He was enjoying a bite of food and a slurp of water. I change the water every day, and of course it keeps freezing but at least if they hurry, they can get in a slurp before it freezes completely! The picture is bad but I had to be quick and since it was dark out, there is obviously my reflection in the glass. I will have to learn how to take better pictures through glass at night! But anyways, I now know that at least one little kitty is still around. I'm so happy!
