My kitten threw up after vaccines. Is this normal for kittens?

Updated On September 23rd, 2025

Hello, my kitten vomited 6 hours after recieving 2nd round of vaccines. He seems fine otherwise, aside from a little sleepy. He got his energy back after napping for a few hours, and had a full appetite. Then after he played for a bit he vomited. Other than that, he seems okay but I'm still concerned.

This can be normal! You can see some vomiting after getting vaccines and given that Faelan only vomited once, I would not be too worried. Plus he sounds like he is otherwise acting normally. I would keep an eye on him and if you see protracted vomiting, diarrhea, signs of an allergic reaction (facial swelling, difficulty breathing, then I would be worried and rush him into an ER vet immediately. I hope this helps!

My kitten got his distemper vaccine today and now he threw up.. should I be worried??
A one time throw up I am not too concerned. If he is a little more tired today that can also be normal. I start to get concerned when they have excessive vomiting, difficulty breathing or swelling of anywhere. I would monitor Freddy tonight if he only vomited once and otherwise acting fine. If he continues to vomit or has any other symptoms, I would recommend bringing Freddy to the veterinarian to have him evaluated. Vaccine reactions are rare but they can happen. Thank you for using Boop by Petco.

Hello, Our kitten got his first vaccination yesterday and this morning he vomited up his undigested food. Our local vet is closed today and I don't know if this is serious. He's been acting normal but I'm just concerned, Thanks, Amanda
Hi Amanda! I'm sorry that Mongeau vomited today. You can see vomiting as a side effect of the vaccines, and it's only a concern if it's protracted and continuing vomiting. Given that he only did it once, I wouldn't be too concerned. Keep an eye on it, and try feeding him some boiled white meat chicken (no bones) in small amounts to see if that helps settle his stomach. If he vomits the chicken, then I would be concerned and recommend you take him into a vet right away. You can see if there is an ER vet in your area; If not, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website. I hope this helps!

My male cat. took vaccinations last on Jan 6th (sun) in Petco He took Feline 3 in 1 (FVRCP) and Rabies Vaccination same time. also vetco tag is 19043910. My concern is he trowed up most every day and diarrhea most of the time. Now is better but s
Yes getting 2-3 vaccines at once is very normal for cats (probably 80+% of cat vaccine appointments). If vomiting occurs right after vaccines (within 12 hours) I would be concerned about a vaccine reaction. But if it's further out than that it's almost certainly not related. Diarrhea is not a common vaccine reaction, so overall I'm concerned something different is going on with your kitty. Since he's back to normal now, I don't think you need a vet visit, but if the vomiting or diarrhea start up again, I'd definitely recommend an exam and discussion. I wouldn't worry about vaccinating him next year from this description.

My kitten recently got vaccinated (yesterday) and her stomach is not reacting well. Today she strained to poop, poop was normal brown colour and on the soft side, but not concerning. She meowed a bit while she pooped then threw up afterwards. She wen
As long as she is behaving normally now, there is likely no cause for concern. She may have had a mild vaccine reaction. If she is due for more vaccines, mention this episode to your veterinarian before the next round. Monitor for continued symptoms and see your vet if they persist or worsen.

My cat had quite a bit of catnip and had thrown up a few times.. he also had his distemper vaccine for the first time today. I am getting worried. Is there anything I can do?
Thanks for using Boop by Petco! Possible side effects after vaccines include pain at the injection site, lethargy, inappetence, vomiting and general discomfort. This should subside within 1-2 days. The vomiting could certainly be due to other reasons like gastroenteritis. If it does not improve or it worsens, have him evaluated by a veterinarian for further assessment and treatment. Otherwise, him will likely start feeling better shortly. Good luck and best wishes!

My kitten had his initial injections this morning, was fine during the day but this evening has been acting a little stange, looks drowsy and shaking.
It can be normal for kittens to be somewhat tired and sore after vaccination, just like human children. Some may run a low-grade fever and not eat well for the first day or so after their shots. What is NOT normal would be any of the following symptoms: repeated vomiting, pale gums, difficulty breathing, or collapse/extreme weakness - these are signs of a serious allergic reaction. This is very rare following vaccination, but if it occurs it can be life-threatening - so if you observe any of these signs, make sure to get your kitten to the vet right away. If she is just tired and sore, it should be fine to monitor her at home - she should be feeling better within the next 24-48 hours.

My cat got his vaccines two days ago and since yesterday I see him sad, sleepy and doesn’t want to eat, today he threw up. It’s that normal or I really have to worry about it?? I don’t like to see my cat like this.
I am so sorry that your cat Milo is ill following vaccines. These are classic signs for a vaccine reaction, and therefore I recommend having him seen by your vet right away. If you vet is currently not open, then I would consider taking him to your ER vet to make sure he is stable and ok. He will likely get medications (antihistamine +/- steroids) to help combat the reaction. I do hope that your pet Milo is able to make a full and speedy recovery. I would notify your vet about this as soon as you can so that precautions can be taken next year when he is due for his vaccine boosters to help prevent this from happening again. Best of luck and take care!

My cat got shots yesterday for the first time she is not acting her self today not feeling well
This can be normal. Getting vaccines can cause a cat to feel off for a couple of days. I'd just keep an eye on Baby for now. If you see a lot of vomiting, diarrhea, severe lethargy, facial swelling, hives, or difficulty breathing, that is not normal and she will need to see a vet immediately. Otherwise, this should pass shortly. I hope this helps!

My 14 week old kitten just got his vaccine two days ago and is having loose stool is that normal?
Hi there. Some pets may have some mild GI upset after vaccinations, so this certainly could be normal. If he's acting normal otherwise (eating and drinking fine, no vomiting, etc.),. then it should be okay to just monitor for now. If it doesn't resolve in the next 2-3 days, or if he develops any other symptoms such as vomiting or not wanting to eat, then I would recommend having him checked by your vet to make sure nothing else is wrong.

Got a new kitten the other day (from a private party as opposed to a pet store or shelter). Took him to a low cost vaccine clinic today where a licensed veterinarian administered the first FVRCP vaccine as well as a deworming medication. The kitten n
This is very common after vaccines. Let him be alone tonight and let him rest. I would not be concerned unless he starts vomiting, having diarrhea, has hives or a swollen face. If any of these symptoms are noticed that I would contact your vet as this is likely a vaccine reaction. Also make sure he is still eating. He may not eat tonight but his appetite should pick up by tomorrow. If he isn't starting to act more normal in the next day or two, contact your vet for an exam.
