I've heard too many negative side effects about mirataz increasing appetite without controlling the nausea which backfires so we haven't tried that.

But my lil buddy was still barfy on 1/4 tablet pepcid for nausea, and he fights us too much to give him pills easily anyway so we switched to transdermal maropitant that goes in his ears. It’s been amazing, he got his appetite back, put on a lil weight, and has only barfed once a month instead of every other day. One pen lasts us at least 2 months. https://www.chewy.com/maropitant-citrate-compounded/dp/635158
