Well, Max didn't see the vet yesterday, but they did prescribe some antibiotics for him--it seems as though his mouth is sore. Lisa says he cries if she tries to touch a certain spot--possibly an abcessed tooth, maybe.
He has started his antibiotics, and ate a half of a can of food yesterday, and a half today, so that's good news.
They are to watch him over the weekend, and if he doesn't improve early next week, he needs to be seen.

Thanks for the positive thoughts and prayers
