And Sammy is home! The doctor's are still confused by the fever he had (it apparantly skyrocketed in the wee hours of this morning but he is now stable and home). I was doing research on the new diet we'll be starting him on once his canned diet is done (He's on Hill's feline I/D?). I'll be posting in the appropriate forum.
Thanks for everyone's support. Hopefully we will NOT have to ever go through this again.
