Late last night around 2-3am 3 out of my 4 cats each vomited. They each threw up once, a small amount of brown liquid mixed with food. They are indoor only cats. They have been taking the same food with no changes. A can of wet fancy feast in the morning and taste of the wild dry food at night. Early last week they were given a few doses of lysine for their herpesvirus but havent been given it since Friday. They haven’t thrown up at all today yet

Hello, sorry to hear about your cats. It sounds like they all may have gotten into something they weren't supposed to (dietary indiscretion). However, any other changes in the environment (new litter, new cleaning supplies, new pets, furniture, or other humans) which can cause cats to disagree with and vomit. Make sure there is nothing around the house that they could have ingested (toys, medications, drugs, plants, etc.) or think back to see if anything has changed in their environments as that could be the cause of their vomiting. As long as they do not continue to vomit and are otherwise, eating, drinking, and acting normally then they should be ok and don't need to see their veterinarian. However, if you are suspicious they may have ingested something they shouldn't have, then please have them evaluated by their veterinarian. Hope this helps and best of luck.
