Louie was punky over the weekend, but perked up some on Sunday. By Monday morning he was one sick kitty and seriously dehydrated, so I checked him into the vet's and started calling every 4 hours for updates. He's home again, I hear (I am not). No clue what was wrong, but he is doing much better. It's only money, after all, and I will feel much better when I can get him to purr for me again.
