I did call the vet's office this morning after I posted and described Branson's symptoms.  She said it was common, but if he isn't better by tomorrow to call and they may want to see him.  He's moving around a little bit more now, but still doesn't want to eat.  Usually he is very active, playing with his toys.  Can't pick him up to cuddle because he cries!   At least he'll let me pet and soothe him.  I hope this doesn't last long.
