Since about three days ago, my nine-year-old cat has been vomiting several times a day. The vomit is a brownish orange color and there are no hair or food particles in it. Usually, she hardly ever throws up or has hairballs. We’ve tried giving her Cat Lax (Hairball Remedy) and Hairball treats, but they didn’t help. Also, I’ve read on the internet that you should put them on a 24 hour fast. Is that safe, and will it work? Does anyone have any ideas about what could be causing this? We are going to take her to the vet as soon as possible. Please help me and my cat!!!
