Diarrhea in Cats: Common Causes & When It's Serious

Any pet parent hopes that their furry friend never gets sick, but sometimes this is unavoidable. When it comes to getting sick, diarrhea is one of the most common issues that can occur in cats. Our Oceanside vets are here to provide insight into the common causes of cat diarrhea, how to treat cat diarrhea, and what the signs of serious illness are.

Diarrhea is an extremely uncomfortable symptom for cats to experience, not to mention potentially quite messy for you. So getting to the bottom of it should take priority. Here are some common reasons why cats develop diarrhea, and when it is necessary to seek veterinary attention.

Why does my cat have diarrhea?

It's not uncommon for cats to experience mild diarrhea due to various reasons such as consuming table scraps or switching to a different brand of food. However, it's important to note that several severe health conditions might be causing your cat's discomfort.

What causes diarrhea in cats?

Some of the most commonly seen causes of cat diarrhea are:

  • Colitis
  • Parasites
  • Viral infection
  • Stress or anxiety
  • Intestinal cancer
  • Change in diet or treats
  • Eating garbage or spoiled food
  • Ingesting toxins or poisons
  • Liver or kidney disease
  • Bacterial infections
  • Pancreatitis
  • Inflammatory bowel disease
  • Medications such as antibiotics
  • Ingestion of foreign objects such as toys and fabric

However, how do you know whether or not your cat's diarrhea will require a visit to your veterinarian? When is it serious enough to warrant medical attention?

When to contact your vet about diarrhea in cats?

If your cat experiences diarrhea, it is important to also consider their other symptoms of lack thereof. You should also keep an eye on their bowel movements to see if the problem clears up. If your cat has more than two episodes of diarrhea in a short period, it could be an indication of an issue, so it's generally a good idea to contact your veterinarian if this happens.

If your pet appears to be struggling to pass stool and is only passing small amounts of watery diarrhea, it could be a sign of a painful blockage caused by the ingestion of a foreign object, such as a toy. This is a serious concern and requires urgent veterinary attention. You should contact your vet immediately or go to the nearest emergency animal hospital for care.

Recurring diarrhea over a short period is usually a cause for concern and might even be a sign of a more serious underlying health issue. This is especially true if your pet is very young, very old, or has a compromised immune system. Some of these infections can be quite severe, contagious, or even life-threatening. You will need to contact your vet and schedule an appointment to determine the cause and develop a plan for how to stop chronic diarrhea in cats.

Cats showing other symptoms in addition to diarrhea should be seen by a vet as soon as possible. If your pet has any of the following symptoms, you should contact your vet right away to schedule an appointment:

  • Vomiting
  • Weakness
  • Blood in stool
  • Unusual drooling
  • Lack of Appetite
  • Signs of dehydration (Sunken dry-looking eyes, dry nose, or dry, sticky gums)

If your cat is showing symptoms that are causing you concern, contact your veterinarian as soon as possible. Your vet will let you know whether or not your cat's symptoms indicate that examination and treatment are necessary.

How to Stop Cat Diarrhea

It is important to note that you should never give your cat human medications without consulting your veterinarian. Many over-the-counter medications that work well for people can be toxic to cats.

When it comes to your kitty's health it is always best to err on the side of caution. By taking your feline friend to the vet for an examination you allow your veterinarian to determine the underlying cause of your cat's diarrhea and recommend the most effective treatment.

That said, your vet's primary focus will be on addressing the underlying cause of your kitty's diarrhea. Once your cat has received a diagnosis treatment can begin to address the problem rather than the symptom.

Of course, your priority is likely to be stopping the mess. To address your cat's diarrhea your vet may prescribe a kaolin-pectin anti-diarrheal medication or another suitable drug as well as recommend one or more of the strategies below.

Other things to consider:

  • Changing Your Cat's Diet: Changing your cat's food may help to rectify the issue. If you have recently changed your cat's food go back to serving the food you gave them previously. If you haven't changed your cat's food recently try switching to a gentle GI food for a couple of days or switching your kitty over to a hypoallergenic or low-antigen diet.
  • Supplement Your Cat's Diet With Probiotics: Probiotics may be recommended as a dietary supplement for your cat, to address the balance of microbiome and reduce GI upset.
  • Increase the Amount of Fiber in Your Cat's Diet: Increase the fiber intake of your feline friend by trying them on a low-fat, high-carbohydrate diet that includes foods such as potatoes or rice mixed with chicken, turkey, cottage cheese, or yogurt.
