Thank you everyone for your support and prayers.
Jerome is back home, still weak and with a little diarrhea, but the vet told me that it can take a little while before his diarrhea stops. It's not watery (sorry don't mean to be graphic) at least. No more vomiting either, however, the vet told me if he throws up or the diarrhea gets bad to take him to the emergency clinic.
He has to take 4 types of medicine my poor baby!!!
The vet told me to feed him boil chicken and rice and of course his id food, but only 1 tsp several times a day.
He is sleeping right now.
