First off, Welcome to PT, and secondly, what a sweet adorable widdle kitty. Bless you for taking him in to care for. Gosh what a sweet face. I'm happy to hear that you brought him to a vet right away to get checked out.

How is he doing today? Has his shivering stopped? Is he eating well? Sorry for all the questions.

How are the widdle guys stools? If he has diarrhea, the best thing that had helped with my widdle ones, was to mix his food with some Baby Rice Cereal for about 2 weeks. This will help bind his stools.

Hope to hear more from you on this precious little one.
