Chronic vomiting is a sign of an underlying disease and can be caused by a number of things including foreign bodies, gastrointestinal strictures or blockages, infections, liver and kidney disease, pancreatitis, abdominal tumors or adhesion, and cancer.

Left untreated the vomiting itself leads to dehydration, electrolyte imbalances, malnutrition and subsequent weight loss. Your cat needs to see a veterinarian. They will do a physicalexamination, run blood and urine tests and possibly do further tests like x-rays.

The blood and urine testing is necessary to get an idea of organ function, immune response, electrolyte levels and dehydration. Kidney failure is not uncommon in older cats and is one of the first things that needs investigation. Prognosis and treatment depends on the underlying cause.

I urge you to take your cat to the vet. If cost is a concern, you may be able to arrange a payment plan with your current vet. There are also charity vets around.

You should take your cat to the vet. Most vets will allow you to make small payments at a time if you don't have much money or even give you a discount. It might not even be that serious and you and your cat will feel so much better once you find out what's going on. You could feel guilty for the rest of your life if you don't at least just have it looked at. Good luck to you and your baby.

The yellow liquid is bile--stomach acid.  There are many causes of vomiting.  The gastrointestinal tract is the stress organ in dogs and cats.  The problem may be primarily with the gastrointestinal tract or it can be secondary.  There is not much you can do at home since your cat is vomiting--the cat would vomit oral medications or fluids.  Causes can be dietary indiscretion, intestinal parasites, liver disease, kidney problems, diabetes, cancer, colitis, and stress.  Once a cat starts vomiting it is at risk for dehydration--this causes secondary complications and lethargy.
Your cat needs to be examined by a veterinarian, may need blood work and x-rays taken.  Treatment may involve supportive care; fluid replacement, and injectable medications.

Occasional vomiting in cats is not unusual.  Most cases of acute vomiting will resolve with simple treatment without the underlying cause being discovered.  If the vomiting is more severe or persists for some time, investigation will have to take place into the problem behind the vomiting.  Vomiting in cats can be caused by a range of things including dietary indiscretion, food intolerances and allergies, worms, infection, blockages like foreign bodies and hairballs, systemic disease like kidney and liver disease, and metabolic disorders.
If the vomiting has only been going on for a short time and your cat is otherwise bright, alert and well, you can initially treat the problem at home.  Withhold food for 24 hours.  Allow access to clean fresh water, and you can use lectade or another oral rehydration solution to maintain hydration.  After 24 hours, provide a bland, low fat easily digestible meal of cooked chicken and rice.  Over the next 48 hours gradually reintroduce your animal’s normal diet.  If your cat shows any signs of clinical illness like lethargy, depression or diarrhoea, contact your veterinarian.

You could try changing the food he is eating, older cats can develop intolerance to certain ingredients.
However, given his age, I would take him to the vet and, if you can afford it, have a blood panel done. It may be unconnected to his earlier puking (once a week is almost normal, in my book) and be a sign of something else. Better safe than sorry

This is usually in cats. When they have some problem in digestion they eat some plant which helps them to vomit. If the cat keeps on vomiting for two to three days then consult a vet

I had a cat for 24 years and every spring he would bring up clear liquid that I thought was from the stomach. Come to find out by bringing a sample to the Vet, was that it was mucus be coughed from the lungs. He had allergies!!! They way I could tell was that it was clear mucus and a little "foamy". Hope this helps.

I have the same thing happening, and my vet said it was allergies! I guess so, because they only did it once.

Usually if they have thrown up a lot or something there is nothing left in their stomach so clear liquid or stomach acid comes up.

This could be something or it could be nothing. 
Sometimes cats vomit up some clear fluid if they have a hairball stuck and they are having trouble bringing it up.  In this case you can try some over the counter hair ball remedy to help him/her out.

More serious causes for vomit include: String gut (which is when a cat swallows string, yarn, tinsel, fishing line etc. Usually while playing).  String gut is a medical emergency because the "string" can get knotted up in the intestines and deprive the intestines of their blood supply.  This can become fatal quite quickly if not treated (surgery).

Another cause of vomiting is poisoning.....obviously a serious issue, and needs to be checked out.  Some common causes of poisoning are; household plants, antifreeze, spoiled food, cleaning chemicals, recreational/prescription human medication.

Yet another cause of vomiting is organ disease (ie. Kidney, liver, heart, pancreas, etc). This tends to be more of a progression of illness however.

Bottom line.....if you are concerned, have your cat examined by a veterinarian.  Make sure you can provide your veterinarian with all the information you can.  For example.....is the cat drinking/peeing more or less than usual?  Eating more or less (not eating is a BIG red flag that SOMETHING is wrong) than usual?  Is the cat's coat nice and sleek looking or does it look messy?  Is the cat less playful?  Certain information about "normal" cat stuff can tell your veterinarian a lot.
Good Luck

I do not know much about cats but I would take the cat to the vet and find out what is wrong with it. It may be nothing and it might. It could be an upset stomach. Atleast watch it for a day and if she gets better then your fine if it gets worse go to the vet.

I think it is just something he ate, or could be an illness. This is the same thing that happened to my 13 year old cat but he does not do it often. You could try feeding him grass, because it sometimes helps digestion. My cat has a problem already and he is on medicine anyway. Take your cat to the vet and see what is the problem.
Good luck!

I would take her to the vet, especially if you are noticing blood in her stool, the white foam can be caused from hair-balls, but I would definitely take her to the vet.  Good-Luck

Your cat has an upset stomach and the yellow foam is bile. Give your cat some fresh grass to eat. Grass aids in upset stomach's and hairballs in cats, it also helps dogs with stomach issues too.

How to tell if your cat is actually sick? The first and most obvious sign of a problem with your cat's health is vomiting. If your cat is vomiting a yellow bile type liquid it can be the signs of kidney failure. Some longer haired cats will cough up hairballs. Long haired cats should be fed hairball food and petromalt to prevent the vomiting. The next most common symptom of a sick cat is if its not urinating in the litter box, it may have a urinary tract infection. If the cat's urine has blood in it or smells extremely acidic, then you should bring the cat to your veterinarian and have a urine test done to determine the problem with your cat. Although some cats (especially male) will occasionally urinate outside their designated litter boxes because of behavioral issues not health related issues. Also sometimes cats just don't like the type of litter you are using. Therefore you can change litters to try to remedy this problem. An excellent litter for sensitive cats is Yesterday's news, it is very soft on their paws. These are the most common and usually the first signs of a sick cat. If your cat is displaying these problems then I recommend making an appointment with your veterinarian. Good Luck!

Yes, and check her stomach. If it's distended, she could be constipated and will need to be seen to by a vet as they can't sort this out on their own.

Could also be hairballs and you get stuff to sort that out too.

But do check it out.

Vomiting is forceful expulsion of stomach contents. These contents can be digested, or containing bile. If only undigested food is expelled then it is called regurgitation not vomiting.

Vomiting in cats can be related with foods and feeding habits like
  1. Changes in food
  2. Food allergies
  3. Food intolerance
  4. Eating rapidly
  5. Exercise immediately after meals.
  6. Intestinal parasites
  7. Gastrointestinal infections
  8. Hairballs
  9. Cancer
Diagnosis requires physical examination, medical history and many lab tests. Treatment depends upon underlying cause. So, it will be good to take your cat to vet.

I just had this happen to my cat only two and half years old, apparently bladder infections are very common for cats and that is what the vet thinks he had.  I am hoping it is not too late for him, he has been there over night as he was very dehydrated and the vet thinks his bladder may have burst resulting in the fluid coming up.  I would suggest that if the fluid coming up is not normal or this happens for more than a day or two, play it safe and get your cat to the vet.

Yellow or white mucus vomiting means unproductive vomiting. If your dog vomit bile or white foam occasionally and don't have any sign of illness then no need to worry. Only persistent cases of bile vomiting should get medical attention. One of the reason of bile vomiting in dogs is bloat which is dangerous and should be treated as early as possible. Following are some common causes of bile or white mucus vomiting in dogs.

1. Rapid eating
2. Canine bloat
3. Overeating
4. Nervousness
5. Stress
6. Dry foods
7. All those foods which can cause irritation in GI tract

So, it will be better to get advice from your local vet.

The kitten has an infection, but blood in the stool is usually caused by tf or coccidia. Take this kitten to the vet as soon as you can.
