Causes of Cat Throwing Up Water

Throwing up water can be a common issue with cats, which can often cause alarm in owners. The causes are typically related to oral health and digestive issues. Common causes of a cat throwing up water include dental problems, such as gum disease or gingivitis; infectious conditions, like salmonella; stomach inflammation from eating poor quality food; blockages from foreign bodies; and pancreatitis.

An undiagnosed medical condition, such as kidney failure, may also lead to a cat forcibly vomiting up water. To ensure good health and reduce incidences of vomiting water associated with these conditions, it is important that cats receive regular health check-ups and have access to quality nutrition.

Causes of Cat Throwing Up Water


Dietary Issues

Many cats experience occasional bouts of vomiting, but when this happens with water, it can take many forms and often has a variety of causes. It could be dietary issues such as eating too much food or too quickly, consuming toxins in their environment, intolerance to certain foods, or a reaction to a new food they are not used to.

In addition to vomiting clear liquid such as water and bile, other signs of digestive issues can occur such as decreased appetite, changes in fecal consistency, or constipation. If any of these symptoms occur along with the cat throwing up water, then it is important that you take them to the vet for an assessment and treatment.

Dietary Issues


Gastrointestinal Problems

It is not uncommon for cats to suffer from gastrointestinal issues that can cause them to throw up water or their food. While this can be quite alarming for owners, the reason for a cat throwing up water may have various underlying causes. Diet, environmental allergies, parasites, and more can all be triggers that lead to cats vomiting clear liquid.

If the issue is recurrent it is best to take your cat to a veterinarian who can provide a diagnosis of the underlying problem and an appropriate treatment plan. Additionally, asking your vet about the types of food you should be providing your feline friend with can help reduce frequent episodes of vomiting.


Kidney Disease

A common cause of cats throwing up water can be the result of underlying kidney disease. In cats, kidney disease occurs more frequently than in other species and can often go unnoticed since it carries a wide range of symptoms. These can include anything from weight loss and vomiting to changes in drinking habits, with an increase or decrease in volume being observed.

If you notice your cat throwing up water, it is important to visit a vet as soon as possible as this could be an indication that something more serious may be going on, such as kidney disease and early diagnosis is key when it comes to successfully treating any health issue your pet may have.

Kidney Disease


Intestinal Parasites

Many cats experience throwing up due to the presence of intestinal parasites. Common culprits include hookworms, roundworms, tapeworms, and Giardia. These parasites attach to the walls of the cat’s intestines and feed off their blood and other bodily fluids, which can lead to vomiting.

Other symptoms that may also be seen include an increased appetite without weight gain, diarrhea or constipation, dehydration, poor coat condition, and lethargy. If you suspect your cat has intestinal parasites it is important to take them to a vet for diagnosis and treatment as soon as possible in order to avoid future health issues.


Viral Infections

Viral infections can be one of the primary causes of cats throwing up water. Feline calicivirus and feline herpesvirus are two highly contagious viruses that can lead to vomiting in cats. These viruses cause inflammation and create congestion in a cat’s upper respiratory tract, which can result in frequent coughing, sneezing, eye irritation, nasal congestion, and purulent ocular discharge.

Though often mild, serious cases can cause poor appetite and dehydration due to excessive vomiting. If your cat is exhibiting any of these symptoms, contact your veterinarian immediately as they may need to prescribe medication or administer fluids to help with dehydration.

Viral Infections



Kitty throwing up water can be a sign of excess stress in their lives. The most probable causes of this could include environmental stress such as loud, jarring noises like fireworks, or changes to the home environment like people moving in or out.

If a cat’s routine is drastically changed and they are having difficulty adjusting, excessive grooming may cause them to throw up water as well. Talk to your vet if you’re concerned that your cat may be under extended periods of stress, as mental health can be just as important for our feline friends as physical health.
