If you have noticed any blood in your cat’s feces, you should certainly be concerned.

This is a sign of a serious problem that needs to be addressed right away.

There are a lot of different things that this can mean, as well as possible treatments.

Normal Cat Feces

A cat tends to produce feces that are around 2-3 inches long with light brown coloration. These animals tend to defecate just once per day. It should be fairly solid and not too runny. If you gently pick it up with your hand, it should hold its shape.

Identifying Blood in Your Cat’s Feces

If there is indeed blood in your cat’s feces, you will probably notice that it has a red coloration. It will most likely be a combination of light brown with some red spots. It ultimately depends on how much blood is in their stool.

When the blood in your cat’s poop is coming from their small intestine, it will probably have a brown or even black coloration. Blood that travels from the lower part of your cat’s intestines or from the anus typically appears bright red.

Causes of Blood in a Cat’s Feces

There are multiple possible explanations for the blood that you have found in your cat’s stool. Some of these explanations are more serious than others.

  Why Is My Cat Throwing Up?


It is possible that the blood in your cat’s stool is due to an infection of some kind. It could be a bacterial or fungal infection that has gone unchecked for too long. These infections can become very serious if they are not treated quickly.


There are certain types of parasites that burrow into the intestines of cats, which often results in bloody stool. These parasites can cause a lot of harm to your cat within a fairly short amount of time.

Some of the more common signs of intestinal parasites in cats include sudden weight loss, lack of appetite, diarrhea, and vomiting. Depending on which type of parasites your cat has, you might be able to see them in their stool. They can appear as small white specks, so you will have to look closely.

Inflammatory Bowel Disease

Cats that have inflammatory bowel disease can produce bloody stool. This is due to all of the additional strain that is put on their body when defecating. If your cat has IBS, you might also notice vomiting, bloating of the stomach, and yowling or whining from abdominal pain.

While this condition is not life threatening most of the time, it does need to be treated promptly. The longer your cat goes without receiving treatment for its IBS, the worse its symptoms will become.


Cats that sustain trauma to their anus can produce blood in their stool. There are a number of different ways that this can happen. Your cat could have gotten into a fight with another cat or some other animal. You should make a point of checking their rectum to confirm that this is not the case.

Sudden Change in Your Cat’s Diet

Make sure that you transition your cat to their new food slowly to avoid such a reaction. Check this article to know more: The Best cat Food.

Treatments for Blood in Your Cat’s Feces

Most of the things that cause blood in a cat’s stool can be treated with medication or by some other means.


If your cat is bleeding due to a bacterial infection, a course of antibiotics should clear it up entirely. Keep in mind that some bacterial infections are more serious than others. The sooner the infection is addressed, the better off your cat will be.

Medication for Parasites

If parasites are the cause of your cat’s bloody stool, there are medications that your veterinarian can prescribe. These medications are usually very effective when it comes to killing parasites in a cat’s body. It could take up to a few weeks before all of the parasites and their offspring are killed.


Sometimes surgery is required to correct a problem with a cat that is causing bloody stool. This is often the case if the cause of this symptom is cancer or an intestinal blockage. The likelihood of success depends on the age of your cat and the nature of the problem.

You need to remember that surgery always comes with a risk, whether it is for cats or humans. It is important that you weigh the pros and cons carefully before making a final decision. You should also consider the advice that your veterinarian gives you very carefully.
