My 3-week-old kitten is vomiting milk and won't eat. What should I do?

Updated On September 23rd, 2025

My 3 and a half week old kitten just vomitted milk twice tonight. I feed her kitty milk and just introducted to him kitty food that says 1 to 12 month. Hes having a cold so the vet said to put in some med in his food. When he vommitted the first time it was just milk and started meowing for his bottle. The second time it had tiny peices of meat but doesnt want his bottle and i think hes going for the third time. Its too late to go to a vet rn. Any thing i can do to make Zaytoune feel better?

It certainly sounds as though Zaytoune isn't feeling well! At 3.5 weeks old, we need to be sure kittens are eating every few hours to keep their blood glucose (sugar) levels adequate. If blood glucose becomes too low, animals can become lethargic and even begin to seizure in severe cases. Possible causes of vomiting could include gastrointestinal upset from his medication, diet change, a virus, etc. Since he is so young and not keeping milk or food down, I would recommend taking him to an emergency veterinarian as soon as possible to assure that his blood glucose levels are appropriate.

    Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Mixer. Sounds like he is very sick and needs to be seen immediately by a veterinarian. Milk should never be given to a kitten. A kitten this old may have already lost the ability to digest milk and by giving him milk, he may develop vomiting, nausea, and diarrhea just like a human who is lactose intolerant. Your vet can take a detailed history and perform a physical exam. Once those are done, a diagnostic/treatment plan can be discussed and implemented. Possible tests include a fecal/blood/urine tests and possibly some x-rays. This could be due to intestinal parasites which is very treatable and could reverse Mixers condition. He may also need fluids, electrolytes, and some external heat to warm him up. Please get him seen immediately. I hope he does well and starts to feel better soon.

    I am most concerned about how the vomiting may be affecting the kittens hydration status. At such a young age, kittens can become dehydrated and hypoglycemic (low blood sugar) very quickly. For this reason, I recommend you have him seen by your veterinarian right away. There are many causes for vomiting including parasite (worm) infections and viral disease amongst others. Overeating is not likely to cause vomiting. Your veterinarian will be able to determine what is going on and prescribe appropriate treatment.
