Very tricky one, if the steroids dont seem to have improved his appetite. SEB would have been another one of my suggestions, and the third would be a tablet appetite stimulant, Rosie was given that when her globulin was sky high, I forget the name of the tablet though, and not sure whether I kept the box - it did work for a couple of days though, but she was a butter to medicate. i would actually go for a/d rather than liquivite, not had any success with liquivite. I would give the vet a quick ring and ask when they would expect to see the steroids kicking in and helping his appetite.
