What is Diarrhea in Cats?Cat Diarrhea: How to Manage

Diarrhea is known as a loose or liquid stool. It can also be characterized by an increased frequency of bowel movements. When a cat is suffering from diarrhea, their digestive system rapidly moves food and other digested material through their body, causing the typical signs of diarrhea to occur. This condition can either be brought on by something that your cat has consumed or something more serious like an infection or chronic illness like a kidney disease.

Depending on the cat, their diarrhea can either be one or two occasions or be continuous for days. If your cat is experiencing diarrhea for more than a day, that usually means it’s time to be checked out by a veterinarian. Dehydration can quickly set in if a cat has been suffering from diarrhea for an increased period of time. Regardless how severe your cat’s symptom is, make sure to provide them with a fresh bowl of water and encourage drinking as much as possible. Another diarrhea treatment is to find some probiotics for cats. Probiotics for cats will help treat your cats digestive tract to get their stool and bowel movements back to normal.

What Are the Main Causes of Diarrhea in Cats?

As said before, the possible causes of diarrhea in cats are endless. Diarrhea is one of the most common symptoms that surface when a cat is suffering from an underlying health issue. This section will cover the most common causes of diarrhea in cats.

Causes of Diarrhea in Cats

  • Change in Diet
  • Parasites
  • Infection
  • Allergic Reaction
  • Kidney disease
  • Tritrichomonas foetus
  • Feline panleukopenia

Change in Diet

Starting off with the least severe, a simple change in diet can cause your cat to suffer from digestive issues. Cats are known to be quite picky eaters, however, that doesn’t mean they never get into things they shouldn’t. If a cat consumes too much grass or any type of foreign object, that may be the cause of their digestive problems.

Cats can even experience this unfortunate symptom just by having a change in their everyday food diet as well. Switching from wet to dry food or vice versa can upset your kitty’s sensitive tummy. If your cat is experiencing these side effects from a change in diet, go back to the old product or slowly add the new product in.


Gastrointestinal parasites like from the protozoan parasite giardia is a likely cause of diarrhea in cats. Our pets can acquire parasites directly or indirectly but are usually ingested through feces from an infected cat. Once an animal has been infected with this parasite, the most common symptom they will show is diarrhea. If you believe your cat is suffering from this kind of parasite, take him to the vet for further analysis. From there, your vet will be able to run several tests and rule out all other possible causes. Once they determine the exact type of parasite, they will then prescribe medication or another outpatient treatment plan.


Both bacterial and viral infections can cause your cat to experience diarrhea. All it takes is a cat to come into contact with a harmful bacteria or virus for them to get sick. Generally, if a cat has an infection, they will also show other accompanying symptoms like a fever, vomiting, lack of appetite, or skin inflammation. Luckily, once a vet diagnoses the cat, they can be prescribed an antibiotic, topical treatment, or pain reliever medication depending on their condition and type of infection.

Allergic ReactionCat Diarrhea: How to Manage

Allergic reactions are usually the result when the immune system becomes overly sensitive to environmental factors. Just like in humans, cats can have food allergies to different products or ingredients that are commonly found in their cat food. If their allergy is not from something that is consumed, it can also be caused by pollen, plants, mold, perfumes, prescription medications, or even household cleaning products.

If you assume your cat is allergic to something in their environment, take them to the vet to determine the underlying cause. Your vet will start the examination process with a complete physical test followed by blood work. If they assume that your cat’s allergy is caused by something in their diet, they may recommend changing up their daily food intake to see if their symptoms lessen. Once the underlying cause has been uncovered, you will need to eliminate the allergen from your cat’s environment.


Although your cat may seem happy and go-lucky, their emotional stability might not be as perfect as it seems. In fact, cats can develop phobias or feline anxieties just like their human counterparts. Cats can feel anxiety by minor changes in their environment, if they move to a new location, or if a new pet is brought into the home.

Other common symptoms of stress in cats include excessive grooming, excessive scratching, urinating outside the litter box, diarrhea, excessive vocalizations, and a loss of appetite. The best way to calm your kitty’s nerves is to make them feel relaxed. Talk to your vet or other pet behavior professional for techniques on how to deal with a stressed-out feline.

Inflammatory Bowel Disease

Inflammatory Bowel Disease in cats is a group of gastrointestinal disorders. These issues restrict the intestine’s ability to function how it should. Aside from vomiting, cats with IBD will also experience vomiting, lethargy, and weight loss. Although there are a few believed causes, most cases are diagnosed as idiopathic. Your vet will be able to conduct tests and examinations to diagnose IBD and prescribe a specific treatment regimen for your cat to follow.


Some medications can be too strong for a cat’s digestive system, causing them to vomit or suffer from diarrhea. Most of the time antibiotics are to blame for these side effects. That’s why it is critical to pay close attention to your cat’s overall health and behavior while they are recovering from an illness. If your cat is experiencing adverse side effects from medication, call your vet immediately. They should
