The holistic vet recommended I try Nux Vomica by Borin (I don't remember the correct spelling of the brand) to help with Panther's vomiting. I went to Whole Foods the other day and bought it. It is packaged in a blue tube and the herb itself is actually in bead form that dissoves in water. I tried it and so far so good. Panther has been on it for 24 hours and so far no vomiting. Yesterday was the first day he was actually able to keep down all of his food.
I know some of you also have trouble with your fur babies so I thought I would give you a heads up. It was under $7 so it might be worth checking out if your cat suffers from IBD or any other stomach trouble. Surprisingly this herb has done more for Panther than all the anti-vomiting and anti-nausea injections combined.
Edited to say that the maximum amount is 3 beads a day for a cat. You don't want to over do it.
