Well, he was hungry!! Another thing we've discovered is that he had fleas on him :( So we washed him with a special shampoo. He seems so much smaller than he was just a few weeks ago when we washed him before. You can see all the bones when he's wet. Of course he has long fur, so you can't see it when he's dry, but you can feel it when you stroke him.
He was so happy to be home. It's really unusual for him to be so lovey-dovey. The first thing he did was lie down on the cold tile floor where the AC air was coming out. It's been really humid these past few days, and when it wasn't hot, it was raining and thundering. I would guess he'd been rained on 3 or more times. That's also a problem, because his fur is all matted, especially on his stomach and neck. It's pretty bad. I think we're going to have to shave him in spots.
