8 Top Reasons & How To Help

Why do kittens get diarrhea? When we first brought home our Maine Coon kittens, we set them up in a separate room with all their bedding, food and water, and litter boxes. They settled in nicely!

I soon found out that diarrhea in kittens certainly happens.

They were perfect in their use of the litter box, fully trained, but it was still a mess.

How Common Is Kitten Diarrhea?

Welcoming a new kitten into your home is such an exciting time, and if you are worried about their health, that can really put a damper on things.

Loose stools are worrying, but it helps to know that it's also quite common

I was worried about the causes of diarrhea in my new kittens, and I immediately called our family veterinarian. He quickly put my mind at ease.

As it turns out, diarrhea in kittens is not uncommon.

It can happen for a variety of reasons, especially when they first come home.

It can be caused by a variety of factors, from dietary changes to stress from a new home.

Some bouts of diarrhea are mild and resolve quickly, while others may require veterinary attention. Let's break it down:


What Is Cat Diarrhea?

Simply put, cat diarrhea involves frequent, loose, or watery stools. When kitty's digestive system is upset, it results in soft stools that can vary in color and consistency.

As a cat parent, whey you see this, you know that your new baby is either feeling unwell, or under stress.


Normal vs. Abnormal Stool Consistency

When it comes to your kitten's stool, it's helpful to know what's normal and what's not.

Healthy stools are usually firm and well-formed.

Soft stools or those with an unusual color or odor can signal a problem.

If things don't look right, it might be time to consult your vet.


8 Common Causes of Kitten Diarrhea

1. Dietary Changes

Why do kittens get diarrhea? One of the most common causes is a sudden change in diet.

Switching to a new food can upset their delicate digestive system. It's important to introduce new food gradually to avoid tummy troubles.

Whether it’s a shift to a different brand or type of food, a slow transition helps their stomachs adjust.


2. Food Allergies or Intolerances

Just like humans, some kittens can have food allergies or intolerances.

Certain ingredients might not agree with your kitty’s system, leading to soft stools or other signs of illness.

If you notice a pattern after feeding specific foods, it might be time to consult your vet about possible food allergies.


3. Parasites

Intestinal parasites, such as worms and Giardia, are another culprit behind kitten diarrhea. These pesky invaders can cause significant digestive upset. [1]

Regular deworming and vet check-ups can help keep these internal parasites at bay and ensure your feline friend stays healthy.

4. Bacterial or Viral Infections

Infections, whether bacterial infections or viral infections, can wreak havoc on a young kitten's digestive system.

Common bacterial infections include Salmonella and Campylobacter, while viral infections like feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV) can also cause diarrhea.

If your kitty is showing signs of illness, such as lethargy or loss of appetite, it’s essential to seek veterinary care.


5. Stress and Environmental Changes

Moving to a new home or experiencing significant changes in their environment can be stressful for kittens.

This stress can manifest as diarrhea. The anxiety of adjusting to new surroundings, meeting new people or pets, and other changes can upset their digestive system.

It's likely that your kitten’s upset stomach is related to these environmental changes rather than an underlying health issue.


6. Overeating or Sudden Diet Changes

Kittens have a tendency to overeat, especially when they find food they like.

This dietary indiscretion can lead to diarrhea. Additionally, sudden diet changes can shock their system.

Feeding your kitty smaller, more frequent meals can help avoid these problems.


7. Ingestion of Foreign Objects or Toxins

Kittens are curious creatures and often chew on things they shouldn't. Ingesting foreign objects or toxic or hazardous items can cause digestive upset.

Keep an eye on what your kitty is getting into and kitten-proof your home to prevent accidental ingestion of harmful items.


8. Underlying Health Conditions 

Although less common, some kittens may have underlying health conditions that contribute to diarrhea.

Conditions such as inflammatory bowel disease (IBD) or other chronic illnesses can cause persistent digestive issues.

If dietary changes and stress management don’t seem to help, it's worth discussing these possibilities with your vet.


In most cases, your kitty’s diarrhea is likely due to more benign factors like stress from a new home or a sudden diet change.

Keeping their environment calm and stable, along with a gradual approach to food transitions, will go a long way in helping them feel better.


When to Call the Vet

Signs That Indicate a Serious Issue

It's natural to worry when your young kitten has GI upset, but how do you know when it's time to call the vet?

Look out for signs of severe diarrhea, such as blood in the stool, persistent vomiting, lethargy, and dehydration.

Honestly, you should never hesitate to call your vet with any question or concern.

Very often, they will consult with you over the phone, perhaps giving you a call back. They will let you know what you can do at home and when to make the decision to come in. They may suggest a supplement or home remedy over the phone.

Duration of Diarrhea and When to Worry

While mild cases of diarrhea can resolve on their own, if loose stools last more than a couple of days, it's time to consult your vet.

Chronic diarrhea can lead to dehydration and other health complications, so keeping an eye on the duration is essential.


Symptoms Accompanying Diarrhea

In addition to loose stools, other symptoms like vomiting, lethargy, and significant weight loss should prompt a vet visit.

These can indicate more severe underlying issues and require a professional to evaluate your kitten's overall health.


Age and Health Status Considerations

Young kittens and those with existing health conditions are more vulnerable to complications.

If your kitty falls into these categories, err on the side of caution and seek veterinary advice sooner rather than later.

An accurate diagnosis of your pet’s condition is crucial for effective treatment.


Professional Diagnosis and Treatment

A vet can perform tests, such as blood work, to determine the cause of your kitten's GI upset. He or she may request a stool sample.

Depending on the diagnosis, your vet might prescribe anti-diarrheal medications, probiotics, or other treatments to help your feline friend recover.

In some cases, dietary changes or specific treatments for underlying conditions might be necessary.

Professional guidance ensures your kitty gets the right care and avoids potential complications.


If you're ever unsure why your kitten gets diarrhea or if it seems more severe than usual, it's best to seek professional advice.

Your vet can provide the care and possible treatments your kitty needs to get back to feeling their best.

In my case, a call to my veterinarian was all that was needed. They prescribed an over the counter remedy, and checked back in over the phone. All was well!


At-Home Treatments and Care

Dietary Adjustments

When your young kitty is dealing with GI upset, making some dietary adjustments can be a good idea.

Offering a bland or limited-ingredient diet can help soothe their tummy. If you’re changing their food, do it gradually over several days to avoid further upsetting their stomach.

Transitioning slowly between kitten milk replacer and solid food or between different brands of wet food can also help.


Hydration and Electrolyte Balance

Keeping your feline friend hydrated is essential, especially if they're experiencing loose stools.

Make sure they have access to fresh water at all times. In some cases, you might need to offer an electrolyte solution designed for pets to help maintain their hydration levels.

If your kitty isn't drinking enough, consult your vet for additional advice.


Probiotics and Supplements

Adding probiotics to your kitty's diet can help restore the balance of good bacteria in their gut.

These supplements can support their digestive health and aid in recovery.

Consult your vet for recommendations on the best probiotics and other supplements for your kitten's specific needs.


Importance of Cleanliness and Hygiene

Maintaining a clean environment is vital when your kitten is dealing with GI issues.

Clean their litter box frequently to prevent the spread of bacteria and parasites.

Regularly wash their food and water bowls, and keep their living area tidy to minimize stress and promote good health.


Monitoring and Recording Symptoms

Keeping track of your kitten’s symptoms can provide valuable information for both you and your vet.

Note any changes in their stool consistency, appetite, behavior, and overall health.

Monitoring their progress helps you determine if the at-home treatments are working or if it’s time to seek veterinary advice.


With the right dietary adjustments, proper hydration, and attention to cleanliness, you'll help your kitty get back to their playful, happy self in no time!


Preventing Kitten Diarrhea

Proper Diet and Nutrition

A balanced diet is key to keeping your young kitty healthy. Stick to high-quality kitten food that's specifically formulated for their nutritional needs.

Avoid giving them dairy products or human food, as these can upset their digestive tract. A well-fed kitty is less likely to have issues with their GI tract.


Gradual Transitions Between Foods

If you need to change your feline friend's diet, do it slowly. Gradual transitions between foods help their digestive system adjust without causing GI upset.

Start by mixing a small amount of the new food with their current food, gradually increasing the new food over a week or more.

Regular Vet Check-Ups and Vaccinations

Regular vet visits are a must for keeping your kitten in tip-top shape. Routine check-ups can catch potential issues early and keep your kitty up-to-date on vaccinations.

These preventative measures are essential in addressing why kittens get diarrhea and other health concerns before they become serious.


Parasite Prevention and Treatment

Intestinal parasites are a common cause of digestive issues in young kittens.

Regular deworming and preventative treatments can help keep these pests at bay.

Your vet can recommend the best parasite prevention plan for your furry friend.


Stress Reduction Techniques

Stress can wreak havoc on a kitty's digestive tract. To minimize stress, create a calm and stable environment for your new pet.

Gradually introduce them to new people, pets, and environments to help them feel secure.

Providing plenty of playtime and affection can also reduce stress levels and promote a healthy digestive system.


Proper nutrition, gradual food transitions, regular vet care, parasite prevention, and stress reduction, are all key to keeping your kitten's digestive system healthy - and preventing bouts of GI upset.
