Poor sweetie! I'll bet that in the next day or so his appetite will return. He was so weak and dehydrated and he needs to get his organs back in balance. As Samantha has said, his body will tell him when he's ready to accept solid food. Of course, we want you home Preacher!! So, get your rest, drink your fluids and get better soon! I'm glad though that the vet decided to keep him until his truly back on all fours, even though I'm sure he'd rather be home with his Mommy and I know how you miss him so. Lots of love and prayers coming your way, Preacher!! Hoping for an encouraging update in the next day or two!!
