Why does my playful kitten vomit in the morning before eating?

I'm sorry to hear Aries isn't doing well! Unfortunately, vomiting like this can be due to a number of things, which is why a vet visit is important. Issues such as a hairball or parasites can cause vomiting, along with functional issues that may be causing problems with digestion. Other issues can include food allergies (male cats tend to be allergic to ingredients such as fish or chicken in their foods) or even an issue with how often you are feeding Aries. Smaller meals more often can sometimes help vomiting if it's every morning, especially if Aries goes all night without any food. Offering a small meal right before bed (or a treat) can sometimes keep the stomach full enough to keep it from getting too empty and causing vomiting. However, since this has been prolonged and there are so many potential causes, a vet visit is always best.

If it has only been twice and this last time was only a small amount, then I would likely wait and see. If there is any further vomiting through the night then I recommend taking him in tomorrow. Our pets are very talented at eating things they are not supposed to without us knowing about it, so I never take for granted the possibility. There are many reasons for vomiting, and if it resolves on its own, then nothing further is necessary.

It's possible Luna may just have some minor GI upset, or she is going too long in between meals if this has only happened twice and she is otherwise normal and happy. Other possibilities can include something such as a hairball that is leading to vomiting. Offering a bland meal after she vomits, or increasing the number of meals she gets per day may help with anything minor. If the vomiting continues, worsens, she shows other signs of illness, or you are just very concerned about it, it is always best to schedule a veterinary visit to rule out more serious issues. Internal parasites, GI illness, metabolic diseases, etc can all potentially cause vomiting as a symptom, so a complete exam is best to rule out any more serious problems.

I recommend getting your cat seen by your vet or an emergency vet right away. Cats need to eat, if they go more than a few days without eating they can develop serious liver problems which can be fatal. Continuous vomiting for so many hours is very exhausting and dehydrating, so your kitten likely needs some medical intervention to get better. Your vet will do an exam, labwork, possibly x-rays, and based on these results, your vet will have a better idea what is going on and can better advise you about treatment options.

Try feeding smaller, more frequent meals. If Smokey eats fast, try a 'slow feed' bowl to address the issue. Sometimes, switching to a canned food may help. If the vomiting persists or worsens, have him examined by your veterinarian.

Vomiting is never normal but it does happen fairly often to kittens. The most common cause of vomiting is eating too much food. Some kitten are just greedy, they eat more than they need. Kittens also vomit because they ate something that they normally don't get ( eating human food, scrapes, scavenging in general). Shadow's problem should settle down by itself. You should withhold food for Shadow for 4-5 hrs and then offer very small amounts every 1-2hrs. He also should be offered only small amounts of water as drinking plenty of water will probably trigger another vomit. Some kittens may vomit because of intestinal worms or gut infections. In that case, they often develop diarrhea, become lethargic and go completely off food. If your Shadow is showing these symptoms, you should take him to your local vets for a check.

Yellow foamy vomit can sometimes indicate reflux or a very empty stomach. If it's only happened rarely, you can try offering food in smaller amounts more often to help keep Ravioli's tummy full and see if it helps. If he vomits more often, or seems lethargic or otherwise ill, or the vomiting continues intermittently even with a change in meal times, a vet visit is a good idea to rule out any more serious issues.
