Got the results from the vet late Friday. His one elevated liver value is back to normal, the other is still slightly elevated. His red/white cells are looking much better. He's done with the antibiotics (liquid) and the antioxidant (also a liquid) for now. He will go to the ferret sitter tonight with just his steriods. He's still not eating kibble, but perhaps being around 5 other ferrets for a week at the sitters will encourage eating. If it does I am seriously going to consider adopting a pal for Sebastian. Thanks all for your good thoughts for my sweet boy.
