I just saw your post (strayed away for a while)... This sucks.
Your old guy can be glad he's not at the hospital, being force-fed crappy food. He gets to be home, yell at you, AND make you prep decadent cat things. Can't ask for more, when you're a 16 yr old cat.
I hope the nausea meds kick in and help some more. Pred can de-flate anything that's angry, so if he's got inflammation related discomfort, that'll help. Poor man.
Keep up the varied menu and patience for the screaming kitty. Lots of cuddles.

I love pus but I hate people.
I can say words like undifferentiated gonads now!
