Share

Cats occasionally throw up. It’s simply a fact of life. Usually, you’d clean it up and move on with your day, but you should check what color your cat’s vomit is. The color can indicate if they have a health problem, and we have a handy cat vomit color chart below to help you. With this information, you can tell when you have a feline emergency on your hands or if your cat only has an upset stomach.

Importance of Checking the Color of Cat Vomit

Your cat throwing up every once in a while isn’t concerning, but vomiting can be a sign that your pet is suffering from a severe illness or chronic condition you aren’t aware of, which could include:

Checking the color of your cat’s vomit can determine if something serious is going on, as can the frequency of your cat’s vomiting. If something is wrong, you’ll likely see other signs, such as loss of appetite, lethargy, or weight loss.

If you’re regularly checking the color of your cat’s vomit and looking for other signs that they could have an illness, you’ll be able to get them to the vet more quickly.

If you need to speak with a vet but can't get to one, head over to PangoVet. It's an online service where you can talk to a vet online and get the advice you need for your pet — all at an affordable price!

Vomit Color Meaning
Clear vomit Clear vomit is your pet throwing up water, usually because they drank too much. Although that doesn’t seem like a big deal, there are underlying conditions, such as diabetes, that can make your pet thirstier than usual. So, a vet visit is necessary if this continues.
White foam White foam indicates the lining of the small intestines or stomach is inflamed and irritated, but there is nothing in the stomach to vomit. Monitor for other signs of illness.
Yellow vomit Yellow cat vomit indicates bile, which occurs when your pet has an empty stomach. Yellow vomit shouldn’t be too concerning unless your pet is also acting strange in other ways.
Blood in vomit Blood in cat vomit can be an indication that there is either an ulceration in the body or a clotting abnormality (caused by toxins or illness). Or, if your cat has vomited repeatedly, the blood could be from an irritated esophagus or stomach. Either way, you should take your cat to your vet for an examination.
Green vomit Your cat’s vomit could be green if it’s mixed with bile (common if your pet throws up on an empty stomach). Another reason could be that your cat consumed plant material. This shouldn’t be concerning unless your pet is exhibiting signs of illness.
Brown vomit Most likely, brown cat vomit is the color it is because your cat’s food is brown, and they ate it too fast. However, it could also indicate traces of blood (especially if it looks similar to coffee grounds and is a darker brown). If you believe blood is in your cat’s vomit, take them to the vet.

Frequently Asked Questions

Cat parents tend to have plenty of questions about their pets throwing up. Here are just a few.

How Are Acute and Chronic Vomiting Different?

Acute vomiting is the type that comes on suddenly and usually lasts only for a day or two. Chronic vomiting occurs frequently, maybe daily or every few days. Both types of vomiting can be cause for concern, especially if they appear with other signs such as lethargy or appetite loss.

What’s the Best Way to Clean Up After My Cat Vomits?

It’s always important to use cleaning products that are not only safe for cats, but that will kill germs and prevent any spread of illness to other pets in your home or to you. At Catster, we have tested all of the cleaning sprays out there, and our favorite is the Hepper Bio-Enzymatic Pet Stain & Odor Eliminator.

Should I See My Vet if My Cat Vomits?

If you think you see blood in your cat’s vomit or your cat is in pain or otherwise unwell, you should call your vet for advice and an appointment. Likewise, if your cat throws up several times a day or once a day for multiple days, you should talk to your vet.

Other reasons to see your vet when your cat vomits include having other signs of being sick, being on medications, and suffering from a health condition like diabetes.

How Will My Vet Treat My Cat’s Vomiting?

How your pet’s vomiting is treated depends greatly on the underlying causes. If it’s something like diabetes or IBD that’s causing your cat to throw up, medication will be critical. But if it’s something with your cat’s food making them vomit, it would require switching to a different kind of food.

Some cats need bland food and time, while others need blood tests, fluids, and imaging diagnostics.

What’s the Difference Between Vomit and a Hairball?

Hairballs and vomit are two entirely different things; the biggest clue you’re looking at a hairball is the shape. Hairballs are long and thin (sort of a cigar shape). While some bile may be hacked up with a hairball, most of what’s on your floor will be hair with some food. Vomit, on the other hand, might have a bit of hair in it but will be made up mostly of fluids.

What Should I Do to Help My Cat When It’s Vomiting?

The best thing you can do for your cat if they’re throwing up is to take note of their other signs and severity and take them to the vet. It’s unfortunate, but there’s not much that can be done to help your kitty at home with vomiting, as there aren’t medications you can give them. One thing you can do is not to give your pet food or water for several hours after they throw up.

But you can help prevent your pet from throwing up in the first place.

  • Try to slow your cat’s eating since eating too quickly can result in vomiting.
  • Keep poisonous items far away from your pet (and remember that some items could be toxic to the cat that you wouldn’t suspect, such as plants or foods).
  • Keep up with regular deworming and vaccinations.

Conclusion

It’s never fun when your feline friend is throwing up, but by knowing what the color of your pet’s vomit means, you can determine whether something is seriously wrong or if the vomiting is a fluke. Other things to watch out for when your cat is vomiting are how often they vomit and whether any other symptoms of illness are present, such as loss of appetite or lethargy. If you feel like something is wrong with your cat, visit your vet for testing and treatment. You can also try to prevent your pet from throwing up by ensuring their food isn’t upsetting their stomach, and they aren’t eating too quickly.

  1. Thank you for your Catster, always a welcome email.
    Regarding hairballs: I have noticed over the years (I am 86) that the hairball usually matches the cat in color. My Siamese cats usually gave me brown hairballs, and my new little love, Lacy, who is a silver colored Lynxpoint Siamese snowshoe, gives me gray to white colored hairballs. Nice article.

    1. Margot Fitsch, thank you for your loyalty and kind comment. You are correct that the fur matches, though the color might be slightly altered by a greenish tint from bile. Additionally, if multiple cats were involved and practiced allogrooming, it's possible that the hairball contains mixed fur.
