I've been giving my kitty Cerenia as needed. That means when he acts nauseous, licking his lips and swallowing, or is vomiting, I give it then, which risks his vomiting it up. I am wondering if I should give him his dose every morning as a preventative. Is that what some of you do? My cat's digestive system is impaired; vomiting is a symptom. But he doesn't vomit every day. That said, I think he is often nauseous but doesn't vomit. Thanks for your input.
