My cats are suddenly vomiting and have diarrhea. Should I worry?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 1 year and 4 months old | 13 lbs

I have two female cats both around a year and a half. And one started throwing up around 3 times. And the other three up more liquidy. I’m not sure how many times. One of them peed outside the litter box and a had diarrhea outside the litter box( again not sure who). They are still playing,drinking water, and just ate. They haven’t thrown up since they last ate. This all happened within the hour? Should I be concerned or did they just get into something.

Vomiting and diarrhea isn't normal, so I would be concerned. It could be one cat is vomiting while the other has diarrhea, or one cat could be having both. Since they both are acting normal, I will give you a home remedy to try for both of them. I recommend withholding food for 12-24 hours, then feeding a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in their normal diet. If the vomiting continues in the absence of food, either of them vomits the bland diet, either of them continues to have diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, they will need to see a vet right away. If you can't tell which one is having the vomiting and diarrhea while trying this home remedy, take them both into the vet to be safe. Best of luck!

My cat recently vomited and then used the used the litter box, some got in the floor. It wasn’t diarrhea and she is running around playing fine. Should I be worried?
It's always a bit worrying when a cat vomits, but since Luna is otherwise acting normally, I can give you a home remedy for her. I recommend withholding food for 12 hours, then feed a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the vomiting continues in the absence of food, she vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away. Best of luck, I hope this helps!

My kitten still eat, drink and play as normal but she's like got diarrhea. And sometime i see a little liquid stool on her butt.. is she ok?? I took her to the clinic to check and inject alr. She was fine yesterday but today she got it again
Diarrhea is a bit concerning, so I can give Koko a home remedy for it. Withhold food for 6 hours, then feed a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the diarrhea continues on the bland diet, she starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away. I hope this helps!

Both of my cats are vomiting. No change in food or routine and nothing strange coming up. They can both hold down water but not food.
I am very sorry to hear that your cats are experiencing these problems, I am sure it is very unsettling for you both. There are a number of potential causes of such clinical signs, including dietary indiscretion, pancreatitis, parasite infestation, infection, and ingestion of a toxin or poison. Because you have only noticed these signs over the course of a few hours I would continue to monitor Them at home. Here is what you can do to help them; Rest Their gastrointestinal tract by holding back food for a few hours. Then you can continue with a bland and easily digested food of the boiled chicken breast, and provide plenty of fresh water. You can also give low sodium chicken broth to increase fluid intake, or flavourless pedialyte mixed 50/50 with water. If They do not improve, have profuse vomiting or diarrhoea, you notice fresh blood, they seems lethargic, in pain or depressed I would advise a trip to the veterinarian. I hope that answer was helpful and more importantly that Y

Poor kitties! It could be one of them has a GI illness or this vomiting could be related to a medical disease such as kidney failure, diabetes, or hyperthyroidism. I can give you a home remedy to see if that helps. I recommend withholding food for 12 hours, then feed a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days.

It could be that Fitz ate something in the house that upset his stomach, causing the vomiting and diarrhea. It could also be that he has intestinal worms. I would make sure he's up to date on his deworming treatments, giving him one if he isn't. I recommend Panacur. You can try giving him a bland diet when he has the vomiting and diarrhea to see if that helps. I recommend withholding food for 12-24 hours, then feeding a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. Given that it's only happened twice in the last two months and he's otherwise acting normal, I wouldn't rush him into a vet just yet. If it continues, then yes take him into the vet. I hope this helps!

The last couple of days my cats have been throwing up. And now they won't eat. I thought it was just a one-time thing but now I'm getting worried. The did get into some raw ground turkey a few days ago but there were fine until the other day. It star
Your cats are adorable! I'm sorry to hear that they haven't been feeling well. As you mentioned, their vomiting could be caused by eating raw turkey, but could also be due to a virus or intestinal parasites. It's encouraging that they are still interested in playing, despite their vomiting. A trip to the vet would be ideal to assure that they are well-hydrated and that there are no other major physical exam concerns. Since this is not an option at the moment, you can try to withhold their food for the next 24 hours, then offer small amounts of a bland diet of boiled chicken frequently. Be sure that both cats are drinking water regularly. You can tempt them to drink by adding a tablespoon of low sodium chicken broth to their water, or offer a bit of watered down meat baby food. If Chloe and her friend continue to vomit, refuse to eat, or become lethargic, you will need to take them to the vet for further evaluation. I hope this helps and that they are feeling better soon!

I feed my cat a can of cat food she had never had before a few days. Later, she started vomiting. Then, after a couple of days of that, she had diarrhea every about three times a day. I took her food away to try to let her system clean out. Can't aff
I am so sorry to hear that both of your cats are having a hard time. To be on the safe side I would not continue to feed this bag of food to your cats.

Because you lrnfirat cat has recovered and you have only noticed these signs over the course of a few days, I would continue to monitor Munchkin at home.

my 7 month old kitten vomited and has diarrhea today. what can i do for him now?
Hi there and thank you for using Boop by Petco to address your concern. If he is otherwise normal and still eating / drinking, I would withhold food for at least 8 hours and initiate a bland diet as outlined below. If he continues to vomit even on the bland diet or he worsens, I would get him examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further. GENERAL INFORMATION A bland diet is a diet that is soft and highly digestible. It is low in fiber, fat and protein and is high in carbohydrates. Bland diets are generally composed of a single carbohydrate source and a single lean protein source. The most common bland diet is boiled rice and boiled lean chicken breast, without skin and bones. Since bland diets are low in fiber, stool production slows and defecation is less f

It could just be Brigid has a GI illness causing the diarrhea. I can give you a home remedy for her to see if that helps. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the diarrhea continues on the bland diet, she starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away. Best of luck.

Hi, this is Yoyo. I have 3 cats. One named Glory(1year and 3months) has diarrhoea for about a month, but she is very active. The rest two named Mara(1year) and snail(3years) are vomiting for a month too. I'll take them to hospital but the appointment
You can't really do anything at home without knowing what is causing the vomiting and diarrhea although it is likely to be either an infection or something in the food as they are all exposed to it. i would recommend trying to make a sooner apointment, this may be more urgent than it seems.
