I think you can safely wait until morning unless the clinical signs seem to persist or get worse. Small cats can definitely dehydrate or become hypoglycemic rather quickly, so persistent vomiting and diarrhea can become a problem. I would also consider separate the sick kitten from the healthy two until you have become certain that there is no infectious or contagious disease. Hope this helps!

    Hello there, and thank you for rescuing these sweet kittens! As long as the kitten who vomited and has some runny poo is acting normal, is still hungry, and has nice pink, moist mucous membranes (which they appear to be from the picture), it's probably safe to wait till tomorrow morning for her to see the vet. Most kittens coming from outdoor environments have some measure of parasites, which could be causing her gastrointestinal upset. Additionally coming into a new home with new food can also cause a bit of an upset stomach. It's best, of course, to have a veterinarian make these determinations, so I'm glad that you're bringing the kittens in tomorrow. If anything changes, such as the kitten continues to vomit or becomes lethargic, you may need to bring her into an emergency hospital today. I hope this doesn't happen, and I wish you the best of luck in caring for these sweet kittens!
