Does your cat throw up white foam?
If you see your cats throwing up white foam, you may be concerned. After all, humans tend to vomit due to an illness — sometimes a severe illness. However, the action and causes for a cat throwing up white foam is actually quite common. If you notice your cat exhibiting such behavior, it’s important to know the possible causes of the vomiting. Then you can decide whether you should take your feline fur baby to the vet.
1. Hairballs
One of the most common causes of a cat throwing up white foam is a hairball. Hairballs occur because when cats groom themselves, they end up swallowing some of their hair. This turns into a hairball in the cats’ digestive systems. Cats should be able to digest this fur — after all, they eat critters with fur and are constant groomers. When hairballs become a problem, it is usually a sign of a lack of digestive enzymes, a problem that is particularly prevalent in older cats.
2. Dietary Changes
Another factor that can cause your cat to throw up white foam is dietary change. Cats sometimes protest changes to their diet by rejecting a meal or eating later than normal. Whether a cat eats or not, her body will produce the digestive juices necessary to break down food. The result is often vomiting.
For the same reason, a change to your cat’s feeding schedule can lead to vomiting white foam.
3. Stomach Inflammation
When stomach inflammation (called gastritis) is the cause of your cat throwing up white foam, it may be accompanied by a lack of appetite. Your cat may vomit bile or blood in addition to the white foam.
Causes for Concern When Your Cats Are Throwing Up White Foam
If your cat is just responding to a change in feeding or has the occasional a hairball, you can relax. However, if your cat’s vomiting is due to gastritis, a visit to the vet may be in order. Other symptoms of gastritis may include sluggishness, dehydration, depression, and stomach discomfort.
Cats eat hair; that’s a fact.
However, they should be able to digest that hair. Sometimes cats need a little help with their digestion. For hairballs, stomach inflammation, and dietary changes, try a combination of Vitality Science’s Pet Flora, Luxolite and Super Pet Enzymes.

I’m so happy I found this site! My 4 year old bobtail cat been throwing up white foam for 2 days she’s never done that! Combined with some out of character and concerning behaviors like urinating and diarrhea on my floors Ive been really scared! She’s still not eating…she tried once and threw it back up! We do have a vet appointment in the morning! I’m going to try the enzymes any other suggestions?? I feed her premium food already and she’s very well groomed so I don’t think it’s a hair ball issue!!
We also have found that adding Pet Flora and Luxolite wi resolve the issue.
My seven year old female cat is fine for weeks until she throws up a hair ball. She spirals down within hours. She develops severe (Gerd), vomiting red foam, won’t eat, lethargic and diarrhea. I have had every test with no clear diagnosis. Just everything is inflamed, gallbladder, IBD and Pancreatitis. The only meds the vet recommends is Cerenia and Prednisolone. Long term this is not a solution. I feed her only can food from New Zealand called Feline Natural. She does well until this happens. Please advise. Thank you for your time.

I have a kitten who just started becoming in heat a week ago it seems my son gave her some of his bran flakes with sugar milk on Thursday mid day after later she threw up her food. Since then she’s been throwing up time to time while foam. I can’t get her to be interested in anything barely water ugh what do you suggest? How long do I wait To go to vet? I’ve tried broth and everything she’s getting nothing in to vomit out is this normal in heat reaction or did cereal milk hurt her?
Many cats are allergic to milk, and sugar and grains can cause inflammation which is probably what is the issue. Try to give them some mashed pumpkin (organic. No spices) and I suggest ordering the Gastro prime combo today! to heal anything that may have been damaged and prevent further illnesses. https://vitalityscience.com/product/gastro-prime-combo-cats/
