That our pet throw up It is not a good symptom, you will think. That is evident. If you have a cat, you will be more or less accustomed to seeing him perform this movement. Although that does not mean that everything in your health is correct. We could say that it is something common, without becoming serious, although at the same time it can be a symptom that there is something wrong. Headaches should come to us in case they become commonplace.

First of all, if your cat has vomiting on a regular basis, it is convenient to stay for a few hours observing what he does. This will allow to check what is the possible problem. You may vomit after eating, after drinking, or simply by being in certain places.

One of the most common causes of vomiting are the hair balls. Cats groom themselves with their tongues, so the hairs accumulate in it and, finally, ingest them. Taking into account that the stomach is not prepared to digest them, they are expelled in the form of balls, helping with vomiting. Not in vain, It is possible to give natural remedies in order to perform the purge in a simpler way.

There are two other causes that can cause vomiting: stress and parasites. The first, the stress, leads to a large number of nerves that cause discomfort and, finally, vomiting. Beware of the situations they live. As for the parasites, these can cause them pains, even internal, that give them bad feelings. If you suspect this possibility, the best idea is to take the animal to a veterinarian.

There are many more reasons why cats can vomit, including the already famous poison. If you see that the cause could be external or you suspect that the health of the pussy is in serious danger, it is best to visit the vet.

The physiology of vomiting

The digestive system has a natural and physiological movement called peristalsis, this movement ensures that the food bolus, which will later be the fecal bolus, runs through the entire digestive tract.

When vomiting occurs this movement is disturbed and becomes a movement that is medically called antiperistaltic movement (since it follows the reverse path), the alteration of this movement sometimes occurs through the central nervous system and on other occasions through the defense mechanisms present in the digestive tract.

Vomiting may correspond to a detoxification attempt of the organism or with pathologies that directly affect the digestive system. Let's see more specifically below what disorders can cause vomiting in cats.

My cat throws up.

Observing the rejected content is important for determine the severity of the case and help the veterinarian identify the possible cause of the problem. The expelled content can be: undigested food, gastric fluid, bile fluid (yellowish or greenish), blood (bright red or brown if it is digested blood), foreign bodies, plants and tricobezoars (hairballs) among others.

The Clinical signs they reveal a lot about the cause of vomiting in cats although, of course, the veterinarian is the only figure trained to diagnose and prescribe a treatment. Yes, in no case should we self-medicate to our feline, since some pathologies have very similar symptoms, so we could cause damage serious and irreversible in your body.

Next we will talk about the most common signals that tutors can perceive and their possible cause:

Why does my cat throw up croquettes?

It can be simply because your cat has eaten a lot of food too fast and his stomach has not had time to digest the food and he needs to expel it. If the food has not reached the stomach but only the esophagus, we will talk about a regurgitation.

In any case, a cat that eats too fast You will need your tutor to ration your food and offer small but more frequent portions, making sure you eat calmly and chewing properly. In case of not doing so, we can acquire an antivoracity feeder.

Why does my cat vomit yellow?

To watch yellow vomit in cats Many tutors suspect that "my cat vomits bile," however, what causes bile vomiting really? Sometimes we will talk about a prolonged fastHowever, it can also be the result of a poisoning, of the presence of a strange body or of various pathologies, such as liver problems or pancreatitis. There is no single cause that causes it, so diagnosis is essential in this case.

Why does my cat vomit foam?

The vomiting with white foam they are frequent and, as in the previous case, they can appear due to several causes, among which we highlight pancreatitis, liver failure, diabetes or renal failure among others. Likewise, it can also be caused by a gastritis or the presence of a foreign body in the organism of our best friend. Visiting the veterinarian is essential.

Why does my cat vomit clear liquid?

That cat throw up water or carry out a excessive salivation it may be due, among other causes, to the administration of some medicine or other foods that have caused a great rejection in our feline. It is frequent, although it would be convenient to look for an alternative so that the administration was successful. We will talk to our veterinarian to explain what happened and request the prescription of another drug.

Why does my cat vomit blood?

The vomit of blood is a very serious symptom, because the chances of a internal bleeding they are very tall. This may be due to trauma, caused by a fall, for example. However, if we observe that vomiting with blood is accompanied by other symptoms, such as diarrhea or seizures, we can also suspect a possible poisoning. Likewise, ulcers could also cause this symptomatology. Immediate veterinary assistance is required.

Why does my cat vomit brown?

A brown vomit may suggest that the cat is also vomiting blood, although in this case we would talk about partially digested blood, what is known as hematemesis. The presence of internal parasitesNeoplasms or gastric and intestinal varicose veins are some of the many causes that can cause it. Once again we talk about symptoms that require urgent assistance.

Why does my cat vomit a lot?

If it is frequent vomiting, with or without diarrhea, without loss of appetite or other symptoms, the cause may be a Alimentary intolerance or one acute or chronic gastritis. If we suspect that this may be the cause, we can fast the cat for 24 hours, however, whether he continues to vomit or not, we must urgently go to the veterinarian to confirm or reject the diagnosis and start a treatment suitable or a diet change. In any case, during the fast we must watch our feline because the absence of food too long can cause changes in the gutty intestinal flora, so it is essential to be very cautious and always consult with the veterinarian.

Why is my cat vomiting and is down?

Most of the causes that we have mentioned throughout this section may cause apathy in the feline, due to the discomfort caused by the physiology of vomiting itself added to the suffering of a pathology. However, as you will see in the next section, there are more causes of vomiting in cats, read on.

Disorders in intestinal absorption

Some disorders such as poor intestinal absorption can cause vomiting and malnutrition in the cat Similarly, metabolic disorders such as hyperthyroidism They can also cause vomiting. Other causes are the lack of digestive enzymes and diseases such as colitis or pancreatitis.

Hair balls (tricobezaores)

One of the most common causes is the formation of tricobezaores, more commonly known as hair balls. When grooming, the cat ingests a large amount of hair that then forms a ball in its digestive system. Later it is expelled in the form of vomit. In this case the vomit will be observed as a cylindrical plug with an accumulation of liquid.

To solve this type of vomit you can brush your cat regularly, thus eliminating dead hair and accumulated dirt. You can also use the malt for cats, a great way to improve your intestinal transit and avoid the appearance of this problem.

Stress and anxiety

Another cause of vomiting in cats is stress. Felines are animals very sensitive to change, let's talk about a change of environment or a food change. If you have moved, you have recently done works in your house, you have changed your food or you have acquired another pet recently, your cat may be stressed and that is the cause of his vomiting. To help your cat you can make sure he has a safe space and quiet in which to take refuge when you want to be calm.

As for food, cats prefer to eat 15 to 20 small portions a day. Leave your daily amount freely available. If you can not help your stressed cat you can consult a veterinarian specialized in ethology who can recommend guidelines or prescribe medication. It can also be useful to improve the home enrichment or make use of pheromones for cats.

Improper feeding

The cat feeding It is one of the most important factors that relate to your health and model it, therefore, we will not get tired of repeating that one of the most important decisions that the owner must make is to acquire a quality feed.

Many feeds contain ingredients such as beaks and bird feathers, animal skin, eyes, brains. etc. Although we can not stop considering them proteins, they are proteins of very difficult digestion, which cannot be absorbed completely cause vomiting. Therefore, we recommend that you inform yourself about how should you choose the best I think for your cat.

Prizes or snacks of low quality

As responsible owners we must take care and love our pet, for this reason we also want to recognize their good actions and offer appropriate treats such as behavior reinforcement or, sometimes, simply because we want to pamper it through food. However, sometimes this action is not as benign or successful as it may seem at first.

If you look at the nutritional composition From these treats we can observe that in many occasions they contain a large amount of chemical additives that the cat's digestive system does not tolerate properly. If we want to use positive reinforcement in cats and give our pet treats, we must first ensure that they contain a nutritional composition as natural as possible.

If the vomiting is caused by these treats, they will be less frequent than when they are caused by a low quality feed and we can identify them more easily because they occur when our cat sporadically ingests this type of products.

Another more serious pathology

If the episodes of vomiting are accompanied by other symptoms such as loss of appetite, fever, bloody diarrhea, constipation, it is that the cause is probably a most serious pathology: may be due to parasites, diabetes, leukemia or cancer. Write down all the symptoms to help your veterinarian in his diagnosis.

It is always useful to take your cat's temperature, ideally it should not exceed 39 ºC. You should also observe your cat well to detect possible neurological alterations such as dizziness, seizures or alterations of consciousness. An increase in thirst, recent jealousy in a cat or urinary disorders are important elements to diagnose the cause of vomiting.

What to do if my cat vomits?

If the cat is an adult cat in good health that has no other abnormal symptoms (such as dehydration, diarrhea or obvious discomfort) we can put fasting from 12 to 24 hours. We will leave within your reach fresh and clean water at all times.

However, if during this period of time you return to vomiting or if after 24 hours and after eating a soft cat diet vomit again, then we will go to the vet urgently. Likewise, it is important to note that in certain circumstances it can be harmful for a cat to stop eating, such as cats suffering from obesity. This is why it is so important always consult with the professional before making any decision.

If your cat vomits again and his level of consciousness is altered, be careful that there is no passage of digestive content into the airways. Keep it away from the expelled digestive material, clean your mouth and airways So you don't get clogged. Keep in mind that in this state you can bite or scratch.

Treatment of vomiting in cats

The diagnosis of these pathologies can be established simply by means of physical exploration veterinary and a blood test or a urine analysis. The veterinarian will begin by performing basic tests and, depending on the results, may request additional tests to help you find the cause of the problem. Hormonal analysis, stool analysis or ultrasound, among others, may be necessary.

Thus, taking into account the cause of the problem and its severity, the professional will prescribe one treatment or another. In the most serious cases, such as poisoning, internal bleeding or dehydration in puppies, you can request hospitalization of the patient for intensive treatment.

In other cases, you will receive the drug or dewormer you deem appropriate for treat the underlying cause of the problem, thus acting on the disorder that is causing it. We remember once again that in no case should we self-medicate our feline, for the serious consequences it can cause.

In some cases, cats may vomit due to indigestion or food overload and presence of hairballs, which causes vomiting sporadically. However, it can also be a sign of diseases such as obstructions in the gastrointestinal tract, presence of any systemic disease, intoxications, malignancies, infections, food consumption in poor or poorly stored conditions, hypersensitivities or immunological problems, etc.

All of the above, if an animal vomits frequently, it is essential to go to the veterinarian, so that the history reported by the owner is properly evaluated, such as: characteristics of vomiting, timing of vomiting, previous illnesses, among others.

What do I do if my cat has vomiting

If your cat has vomiting, if only once, It is important that you observe it and see if they are repeated. When you do this, identifying the problem will be much easier. Then you can act to fight it.

Imagine that you realize that your cat always vomits after eating a certain food. Or after having ingested some kind of herb. If that happens, all you have to do is prevent him from eating that herb or eliminate that food from his diet.

Hair balls

One of the most common causes of vomiting are hairballs. This happens because cats do their body hygiene with their tongue. This means that the hairs begin to accumulate in it and eventually end up swallowing them.

Since your stomach is not prepared to digest them, the way to expel them is through vomiting. In this case, what can help you is to give plants to help you purge.

Eat too much

As it happens to us, cats can also be soaked. This causes an overload of food that the body is not prepared to digest. The way to expel it is with vomiting.

To avoid this problem, we have to control the amount of food our cat eats. Also watch that he does it calmly and chewing correctly.

Frequent vomiting

Occasionally, vomiting can occur if none of the above causes. This could be caused either by some type of food intolerance 1 gastritis.

What we can do in these cases is leave the cat for a whole day without eating and see if the vomiting continues. If that happens, it is best to take it to the veterinarian quickly, since you may have a gastrointestinal infection that will have to be treated.

Thus, if the veterinarian discovers that it is an intolerance, he will do a blood test that will determine what is the food caused by vomiting and will ask you to eliminate it from the diet. If it is a necessary food for the cat, the most normal thing will be to advise another to provide the same nutrients.

Although it sounds strange, cats can also suffer stress. Cats are routine animals, so when they undergo changes, they can get stressed. For example, a move, the acquisition of a new pet or a change in feeding could stress it and this in turn cause discomfort to make you vomit.

Stomach parasites can be another cause of feline vomiting. If your cat has parasites, it is normal to vomit for more than a day, after which you should take it urgently to the veterinarian.

Observing your cat and seeing any change in his attitude or character is essential to identify if these vomiting are something to take into account or not.

However, if you see that your cat is still vomiting after 24 hours, it is best to take it to the vet without fail, since your life could depend on it.

It goes without saying that if your cat has vomiting, it is best not to feed him until they stop.

# 2 Surveillance Diet

If it is an adult cat, without diseases or some other symptom, you can put it on a diet of 12 to 24 hours to allow your stomach to free itself from what is making you sick. Remove the food and give it water in small amounts during the first hours. Then you can give him a soft diet and see if the vomiting stops. If you continue to vomit, take it with the vet.

# 3 Eat very fast

When a cat eats very fast it may have regurgitation (pieces of undigested food, only chewed) or vomit (half-digested food). So that this does not happen you can ration food and give small portions but more frequent. Watch that you get used to eating slowly and chewing well.

# 6 Food intolerance

Did you change your diet recently? Do you usually give "tastes" of your food? If you do not have any other symptoms such as lack of appetite or extreme tiredness, it is possible that some of these foods are causing vomiting. To know it you must put it on an empty stomach for 12 to 24 hours and give it a taste of food little by little. After giving each food, keep an eye on it for a couple of hours to see if it presents or not vomiting.
