Diarrhea in Cats

Diarrhea is pretty common in cats, and there are many reasons why a cat might have it. It isn’t a very serious issue, but it is important to check how frequent it can be. Usually, it might just come and go quickly, and other times it might last for a week or even for a whole month.

Common causes of cat diarrhea

Some of the common things which lead to diarrhea in cats are allergies or intolerances towards certain types of diet or food. It can also be due to inflammatory bowel diseases or even worms, i.e., intestinal parasites. Moreover, colitis, cancer, pancreatic diseases, and hyperthyroidism can also lead to extensive diarrhea.

What to do when the symptoms of diarrhea indicate major health issues

Just in case your cat has been facing diarrhea for a few days, make sure you take it to a vet to understand the reason behind it. It is important to contact the vet as soon as possible, especially if the diarrhea is black or bloody. Diarrhea, along with a fever, vomiting, and loss of appetite, and sluggishness, also calls for consulting the vet right away.

Treatment for diarrhea

In case of diarrhea, make sure your cat gets the necessary treatment suggested by the vet. However, make sure you know the exact cause first. There will be times when the vet recommends a few prescription medications to help control the cat’s inflammation.

A special diet might also be recommended, so make sure you make your cat follow that.

Prevention of diarrhea

 Make sure you don’t give your cat a lot of dairy products like yogurt or even milk. This will help prevent diarrhea, as cats can’t properly digest dairy products. If you switch the brand of the food you give your cat, make sure to give it in small amounts so that the cat’s body can get used to eating a different product. If you don’t do that, it can lead to indigestion, and then eventually, diarrhea.

Cats with constipation are likely to pass on very dry and hard stools. They can be in extreme discomfort during this period.

Another symptom of constipation in cats is restraining from going near the litter box, crying in front of it, and avoiding it. Cats tend to vocalize their discomfort through mainly straining and not going into the litter box.

If you see any discomfort from your cat in using the litter box and not passing stool, it is a major sign of constipation. It might mean that the cat has urinary tract issues. In this case, a vet needs to be contacted.

Constipation can also be a symptom of other issues in the cat as well

These other issues that can cause constipation in a cat include being nauseous, decreased appetite, drinking more water, drinking less water, weight loss, loss of muscle, walking stiffly, hiding, difficulty in jumping, and vomiting.

Constipation in cats is mainly caused when the intestines fail to move things along normally. When things aren’t moving normally, the stool gets hard and dry.

This can be caused due to stress, inflammation, anxiety, nerve problems, bowel diseases, and sometimes even cancer. Other chronic diseases like kidney disease, diabetes, and hyperthyroidism can also lead to constipation. This causes pain as well.

Familiarizing yourself with the types of stool

If you are a cat parent and have a cat pet or a kitten, you might be used to cleaning out the litter box. This isn’t the best activity in the world and might not be fun, but make sure you pay extra attention to your cat’s stool because it can indicate many things. To familiarize yourself with the types of stools and what each indicates, make sure you consult your doctor and read the stool chart.

If your cat passes stool at least once a day, it indicates that the cat is in good health. It is important to familiarize yourself with the types of stool so you will know what to do in case of a ‘bad’ stool. Here are a few lists of questions that all cat parents have, and they are answered to help you through this process.

It’s shaped in the form of an uncooked sausage and is about a little less hard than that. If your cat is passing this type of stool, it is considered healthy. However, make sure that the healthy stool isn’t too dark. Black stool can indicate blood in the stool. Black stool is an unhealthy stool, as it has blood in it, and too light stool means a chance of liver disease. This can indicate obstruction of a bile duct.

If your cat has passed out small and hard balls of stool, it is considered an unhealthy stool, indicating constipation. Hence, this is a serious issue. There are metabolic and neurological concerns and conditions or chances of colon obstruction.

Moreover, make sure you look out for soft and liquid-like stool, which means the cat has bacterial infections. This is cat diarrhea, as explained in the article before. You have to check closely, as liquid stool can be mistaken for urine. Hence it is essential to understand cat stools.

Preparing samples of cat stool

Whenever you visit the vet to get your cat checked, your vet might ask you for stool samples to test it in a lab related to the fecal matter. It is best to prepare the stool samples beforehand and start observing the cat’s stool a week before so that the vet can understand the differences in each of them.

Make sure your samples are pre-prepared and are collected into approved plastic containers before your appointment with your vet.

These containers are available almost anywhere, and you can purchase them online or at any pet supply store. The lab mostly needs a fresh sample, so make sure you make arrangements to get the most accurate results.

Once you put the stool sample into a plastic container, make sure you refrigerate it and jot down the date and time of the collection so that the vet has legit information and can gain accurate results from the lab testings.

If you have a lot of cats, make sure you get all of them checked multiple times

If you are a cat parent of more than one cat, it means that you would have to prepare everything for the vet accordingly. You would have to prepare the sample accordingly and make sure that you know about each cat’s stool condition yourself, and jot down their behavior individually.

It is better to keep a separate litter box for each cat so you can jot down the behavior and the types of stool for a specific period. You should know that your cat stool can tell you a lot about its well-being and health, and when you have a lot of cats, it can be hard to keep a check, but it’s something you have to do.

Make sure you have time to incorporate a stool check and litter box maintenance routine into your daily life, as it is a priority to keep your cats healthy.

Importance of using a cat stool chart

This is an important part of maintaining your cat’s health and keeping a check on its stool. Your cat’s stool is one of the main indicators of its health, and a healthy cat is supposed to have healthy stools.

Abnormalities in the stool that should be noted

The major abnormality in the stools that should be noted is extraneous matter. This extraneous matter mostly includes hairballs. If the stool is soft, i.e., formed a bit mushy, it means it can cause a simple sudden change of diet. More changes might lead to mild or any early cases of diseases which might include causing diarrhea as well.

Another abnormality that is seen in stools is loose feces, i.e., basically diarrhea. This can be caused by many factors, like intestinal irritation as well as bacterial infections as well. Moreover, kidney disease, liver disease, other inflammatory bowel diseases, and food tolerances can also lead to this.

Two types of cat diarrhea

The first type of cat diarrhea is the one that is small intestinal diarrhea, which tends to have a larger pool of stools, which aren’t passed frequently. In this, blood is mostly present, and the stool might be darker. This type of stool is described as tarry, as it has been digested and is passed through the digestive tract.

The second type of diarrhea is the large intestinal diarrhea, which is associated with colitis. In this, smaller amounts of stool that are loose are passed, but more frequently. In this, there might be streaks of mucus and blood as well.

If there is a hard stool, you might want to note it down, as it is the opposite of diarrhea and is mostly passed because of constipation.

If you notice that your cat is over-grooming itself while passing stool, it can suggest that it is in discomfort or has abdominal pain, which calls for a checkup.

Generally, a newborn kitten tends to pass stool more than an older cat. Moreover, when it comes to cats of quite an age, they also tend to skip a day to pass stool.


The cat’s diet greatly affects the amount of stool they pass. A cat usually fed lower quality food tends to pass stool much more frequently than those fed higher quality and healthy food.
