Now this is interesting. Mostly a cat will want to be near the human - the feeding machine!

Is George worried about the dogs? Does he have to be in the bathroom to escape and feel safe? If so, then you need to develop a safe place for him - use baby gates etc. A cat will typically hang out on a comfy chair, sofa or bed, and near the litter box, food and water bowls.

Is the house too hot for him? Bathrooms tend to be cooler, especially if you are in contact with the tile work.

Those are the only 2 things I can think of just now.
