Poor Luvbug! Given that she is on KD, I'm assuming that she has kidney problems requiring the food. I would bring her into the vet today for an exam. It could be that there is an ingredient in the food that causing her to vomit, or her kidney problems could have progressed further to a place where she can no longer keep down food. I'd recommend having blood tests and a urinalysis done to check on her kidney function.
