Pepper threw up a little bit this morning. It was food but he hadn't had anything to eat for at least 8-9 hours. I called the vet again this morning and he said he should be okay as long as he isn't throwing up all of his food. He also said it could be a hairball. I give him hairball stuff every other day but now I have to give it to him every day for a while. I also received a long list of foods that the lab recommends. I didn't expect such a long list. I'm going to try to research some of these and decide which food I want to switch to. Eventually all 3 cats will have to also switch to the new food but for now Storm and Sunny need to finish the Nutro Natural Complete Care Weight Management Formula because I have about 15lbs of this left. The vet also said that I may just have to live with Pepper throwing up a little bit every now and then. The solution is never easy with Pepper. I do think that switching food will help him.
