What Do I Do If My Cat Is Sick

My cat throw up after eating

If your cat is sick once or twice but appears otherwise well, remove their food for a few hours, then feed small amounts of a highly digestible food such as chicken, or a prescription diet from your vet. Allow them constant access to a small amount of water. After 24 hours go back to your usual routine.

Kidney Failure In Older Cats

A senior cat throwing up can be a symptom of kidney failure. After working 24/7 for 12-plus years, the kidneys begin to wear out. For most cats who live 15 years or more, kidney failure writes the last chapter in the cats medical history.

The kidneys job is not to make urine it is to get rid of waste products that are in the blood. When the waste products exceed the high end of the accepted normal range, we say the cat is in kidney failure.

To measure kidney function, we often look at two waste products in the blood: creatinine and the blood urea nitrogen. When they become elevated, the cat has lost about 75 percent of kidney function. That is the bad news. The good news is that cats are not small dogs. When dogs lose 75 percent of kidney function, we use the term kidney failure. These poor creatures are in real trouble and usually do not live more than a few months. However, cats are tougher than dogs. They can live quite well when the kidney values are mildly elevated.

The key is to find out about kidney insufficiency early on, so measures can be taken to prolong kidney function. Kidney insufficiency is a stage of life in which normal kidney function has passed, but in which kidney failure does not exist. The cats annual physical examination should include blood tests for kidney function .

So Do I Need To Worry If My Cat Vomits Regularly

Whilst it is always sensible to seek the advice of a veterinarian if you are concerned about your cat, there are some innocent reasons why your cat may be vomiting. Watch out for other signs that your cat is unwell, and consider whether your cat may be eating too fast, or having trouble with hairballs. Ultimately, a quick call to the veterinary clinic will help to put your mind at ease if you are unsure.

Is Vomiting Normal For Cats

Just like their people, our feline friends can suffer from an upset tummy for a number of reasons.

Some of the most common causes of upset stomach in cats include, a reaction to eating something bad, viruses and parasites, or more serious problems such as cancer or organ conditions.

Pet parents should be aware that if your cat vomits more often than once a month, or keeps vomiting repeatedly, it’s time to see your vet to determine the underlying cause of your cat’s vomiting.

What To Do If Your Cat Throws Up Foam

Why does my cat throw up after eating?

If your cat vomits foam, start taking notes to develop an understanding of what happened.

If you notice that your cat has thrown up foam, its important to make a few observations. Did your cat vomit red foam, which could indicate bleeding in the esophagus? Did your cat vomit yellow foam, which indicates the presence of bile? Taking note of the characteristics of your cats vomit can allow you to provide potentially valuable information to your veterinarian.

Next, monitor your cat carefully. A single episode of vomiting may not require immediate intervention, as long as your cat is otherwise acting normal. Confine your cat to a small area for ease of monitoring and keep an eye on her, but she may return to normal over the next several hours.

If your cat has been vomiting frequently or is showing signs of illness, take them to a veterinarian.

If your cat has three or more episodes of vomiting in a day, however, or if he or she is acting very lethargic or ill even after a single episode of vomiting, you should contact your veterinarian to schedule an appointment for your cat. A loss of appetite that persists for more than one day should also trigger a call to your veterinarian.

Causes Of Chronic Cat Vomiting

We want to make sure our readers understand that no kind of vomiting is considered to be normal, despite what you may have heard. Some reasons behind the vomiting are less severe than others, but no vomiting should be overlooked entirely.

In cases of chronic vomiting, pet owners should be on high alert, as continued vomiting can signal an unresolved medical condition.

Dietary Causes

Food intolerance and food allergies can cause chronic vomiting. Pet owners may not realize that their beloved cats and dogs can develop allergies just like people.

In fact, food allergies are often the underlying cause of cat vomiting that occurs intermittently over a long period of time.

If your cat has normal energy levels, is a healthy weight, and doesnt appear ill but throws up from time to time, you may want to look into whether they have developed a food allergy.

Over time, a cats digestive system can become sensitive to an ingredient and actually mount an immune response against that ingredient. This response can inflame the digestive tract and possibly lead to the development of food allergies.

Removing the offending protein from the diet is the best way to prevent vomiting due to food allergies. A food elimination trial, which is a lengthy and sometimes expensive process, will help your veterinarian determine which protein is causing your cats food allergies.

What To Do If Your Cat Is Throwing Up Yellow Liquid

If your cat vomits yellow liquid one time and there are no other signs of illness, then it may not be a cause for concern. Watch your cat closely for a day or two to make sure he is eating, drinking, and behaving normally. If your cat stops eating, becomes lethargic, or continues to vomit, contact your veterinarian for advice. Your vet may recommend withholding food for 12-24 hours, feeding a bland diet, or coming in for an exam. If vomiting becomes frequent or your cat appears to be in distress, bring him to the nearest open veterinarian as soon as possible.

One Of The Primary Causes Of Throwing Up In Cats Is An Illness That Affects The Digestive Tract


There are many different possible causes of gastrointestinal upset in cats, including parasites, bacterial infections, food intolerance, indigestion, gastritis , pancreatitis , or constipation.

Some cats may vomit because they have ingested a foreign object, such as string or an insect. Other cats may vomit due to a more serious underlying intestinal disease, such as cancer or an autoimmune inflammatory condition.

Cats can also vomit due to systemic diseases, or conditions that occur outside of the gastrointestinal tract. A number of systemic illnesses can include vomiting as a clinical sign, such as diabetes, hyperthyroidism, chronic kidney disease, liver disease, and others. Toxin ingestion may also trigger vomiting, as well as some neurologic conditions.

When considering the potential causes of vomiting in cats, it can be helpful to distinguish between acute and chronic vomiting. Acute vomiting is vomiting that has developed recently and suddenly.

For example, a cat with no previous history of vomiting that vomits several times in one day is experiencing acute vomiting. Chronic vomiting, in contrast, is vomiting that occurs over a prolonged period of time.

Why Do I Throw Up Water All The Time

This can happen because youve already thrown up all the food and fluid in your stomach, youve been drinking a lot of water, or you havent eaten in a long time. Often, it is a sign of a stomach infection, caused by a bacteria, virus, or parasite. Or it could be from food poisoning.

But this will have little effect on how rapidly your body absorbs the alcohol thats present. The most ideal situation to avoid any ill effects from drinking on an empty stomach is of course to avoid doing it by eating some food. Eat at least an hour before drinking if you plan on consuming more than one drink in a sitting.

Cats with a bloated abdomen, lethargy, discoloration of the skin and eyes, and excessive thirst that goes along with gagging and vomiting may have liver disease. This can be caused by ingesting a toxin, but it is most commonly a disease of old age in cats.

Hairballs / Furballs

Hairballs are undigested, wads of fur that clump in your cat’s stomach as a result of the cat’s self-grooming. Hairballs are especially common in longhair cats, and cats that groom excessively. Hacking noises and spasms commonly accompany vomiting if your cat is trying to rid itself of hairballs.

In the majority of cases, hairballs are easily brought up by cats, but if your cat is experiencing difficulties when trying to expel a hairball it’s time to see a vet. Occasionally hairballs become trapped and can lead to intestinal blockages which may be fatal.
