Potential Causes for a Cat Throwing Up White Foam

If you see your cat puking white foam, it is quite easy to become concerned. After all, when humans vomit it is usually due to an illness, whether that illness is severe or not. But a cat vomiting white foam is actually a pretty common occurrence. If you notice your cat exhibiting this behavior, then you want to know the possible causes so that you can decide whether or not it is a reason to take your feline fur baby to the vet.

Hairballs

One of the most common causes of a cat vomiting white foam is due to them having a hairball. Hairballs happen because when cats groom themselves, they get hair in their mouth that forms into a hairball within their digestive systems. Cats should be able to digest fur, they eat critters with fur and are constant groomers. When hairballs become a problem, it is usually a sign of a loss of digestive enzymes. This is a common occurrence with cats, especially older ones.

Dietary Changes

Another thing that can cause your cat to throw up white foam is a dietary change. Dietary changes can sometimes be resisted by cats. That means that they might skip a meal or eat it later than they normally do. If you are feeding them a new food, and they don’t have any warning, their bodies are going to produce the digestive juices that they need to break down that food, whether they eat it or not. As you might imagine, this also means that you if you change your cats feeding schedule itself, then white foam vomiting may be a result as well.

Stomach Inflammation

Stomach inflammation, called gastritis, can be one of the causes of your cat vomiting white foam. Usually, this symptom will be accompanied by a lack of appetite and they may throw up bile or blood in addition to white foam.

When to Panic

If your cat is responding to a change in feeding or you have a cat puking white foam due to a hairball, then you can probably relax. But 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.

For hairballs try a combination of Vitality Science’s Pet Flora and Super Pet Enzymes

Cats eat hair, that’s a fact.

However, they should be able to digest that hair. Sometimes cats need a little help with digestion, for hairballs we suggest a combination of Vitality Science’s Pet Flora and Super Pet Enzymes.

    If your cat is throwing up white foam, yellow foam, no food, small amount of hair…
    Elevate the Food Bowl enough to make your cat eat standing up. Should resolve itself within a few days. This relaxes the digestive tract enough to lower the amount of stomach acid being produced.

    Hi my cats occasionally throw up white foam with a little fur ball but their poops are like little fur sausages with a thin coating of poop – is there something I should be doing about this?

    • LeLa Becker says:

      Hi Karen, Although, JBrown has an excellent suggestion, we would also like to suggest Vitality Science’s Super Pet Enzymes. Adding this to the food will help to dissolve hair and other undigested items in the GI Track. Resulting in my formed stools and expelling more stools from the GI Tract. Thanks for writing in and let us know how else we can help.

    My cat vomits daily some days multilup times. Always after eating and drinking water. Recently he lost bowl control
    This cat is 14 years old so I’m concerned

    My cat is about 3 years old and he recently started losing weight and he WILL eat but throws it up and is continuing to throw up even the white foam if he hasnt eaten. I don’t know what the problem is or how to fix it 🙁

      It is not unusual for the pathological basis of any suffering to be unknown. After all, biological organisms are extraordinarily complex. This is despite so-called modern medical science telling us they understand what is going on down to the gene, and what little they don’t know will soon be revealed. On the other hand, we do know in great detail what natural supplements and nutritional inputs will reverse cats throwing up white foam. I will send more detail to your email.

    Hi, any suggestions on what to use for a my 11 year old tabby with probable IBD? She is ALWAYS hungry, has soft formed poops that STINK, and has lost a lot of weight. However, she is well hydrated, and eats all the time. She does leave SOME food in her dish and sits there like
    she wants something else when there is still food available.

    • Stephen says:

      Hello,

      I recommend the Castro Prime package. It contains enzymes to improve assimilation and Pet Flora to deal with the pathogens causing the unpleasant smell. I will send you more information to your email.

    Hi i have a 6 year old Japanese bobtail. She recently started throwing up this morning. It was the first time yellow with chunks every time after that its been white foamy bile. I tried keeping her away from food and water to see if that would help. But she hasnt gone to eat anything and threw up again. Its been a good 9 times since this happened. Its like 3 small piles . I dont know what to do. Im panicking. I need some answers. I just want my fur baby to be okay and feel better.

    • Stephen says:

      Seems like she ate something toxic. If it gets worse or doesnt resolve in a few days, go to a vet. We have programs for chronic cases (long term treatment resistant). Check out Gastro Prime on our web site.

      The problem is probably the diet. See my food recommendations below.

      Guidance On Food

      We recommend what not to feed. Especially avoid corn, wheat and soy and for some pets carragenan and guar gum. Next, for many pets but not all, no grains and no chicken.

      Next, unless dry is all the pet will eat, no dry. Dry food dries them out. (Who’d would have guessed!) Canned is not so great either. Imagine yourself living out of cans! Canned and dry food are devoid of enzymes and the proteins are denatured. These deficiencies can be remedied with supplements.

      The best is raw but some domesticated animals cannot handle raw. We feed Nature’s Variety frozen raw carried by most large pet stores. Nature’s Variety also sells a very good canned and dry. That said not all animals  will eat Nature’s Variety. 

      Of all the proteins, rabbit, lamb and venison are the best. Avoid all birds (chicken, turkey, duck) since many pets are allergic to them, especially the chicken.

      All food changes should be done incrementally. A 10% change per day is recommended. If at any time the GI problems get worse, then that food is not recommended.

      Avoid too many variables by using only “single protein, limited ingredient” foods.

      Here is a link to limited ingredient single protein food, which has been successful for many but which may or may not be the right food for your pet:

      https://www.instinctpetfood.com/cats/limited-ingredient-diet

      If your cat or dog has a thyroid condition, avoid lamb, venison, and chicken as they are too energetically hot. For hyperthyroid cats and dogs, duck, rabbit and pork are beneficial. Also, for hyperthyroid animals avoid seafood and supplemental iodine.

      For FIP cats no pea protein.

      For cats and dogs with a kidney condition no beef, buffalo, or Bison. (Too many inflammatory factors.) Glandular extracts are OK. High protein raw diets are recommended by many holistic vets but not seafood. (Too much phosphorus.

      Super Carnivore Bone Broth Supplement
      Bone broth can be bought frozen, shelf stable, and refrigerated. But the best bone broth is home made.
      (1) Breville Slow Cooker is recommended. A very slow slow cooker is necessary so that the bones can cook for days.

      (2) Ingredients: 5 lbs bones, 5 table spoons Apple Cider Vinegar, clean water

      (3) Cook on low setting for at least 48 hours. Stop when bones are brittle.

      (4) Although bone broth could be a staple food. It is time consuming to make so the dosages should be adjusted for weight. At least a few teaspoons for a 10 lb animal and a few ounces or more for a 100 pound animal

      Fermented Fish Stock

      You can buy frozen, pre-made fermented fish stock that has helped quite a few very very difficult cases.

    Hi, my 6 year old female cat just started throwing up small piles of clear and sometimes white/yellowish foam. Mostly only seen in the mornings and will wake from her sleep to do it. Still eating and drinking normally.

  9. Shannon says:

    My 8 year old male tabby has been throwing up foam for 3 days now. He only does it once a day, but is not eating. He is acting normal, but refuses to eat and I am not seeing him drink. He is still using the cat pan though, so it may be when I’m not looking or at work. Do I give him a few days or what?

  10. Maegen says:

    My 9 year old Female Tabby/Maine coon, recently started vomiting the white foam with clear slimy liquid. They are indoor cats so my mom came by with some cat grass. They loved it, but a day or 2 later I started noticed the piles of foam.. she is eating and drinking and has wanted more cat grass. She’s eaten soon of it but not like the first batch. I’m use to her vomiting cat food because she eats a lot (she will only eat dry food) then vomits it up… she hasn’t been eating a lot and she constantly wants to lay on me. But the vomiting is 2 or 3 times a day every day. Could it have been the cat grass?

    • Stephen says:

      The cat grass is causing the whiote foam to come up but it is not the cause. Food is your first suspect and then water, and then medications, especially vaccines. I will send relevant docs to your email address.
