What is Pooping Blood?

A cat who is passing blood in the stool may be experiencing pain when defecating. The term for this is dyschezia and may be one of the reasons why your cat is pooping blood. When cats poop blood it can be in the stool only slightly, giving the stool a tint of reddish-pink.  It may also be a bright red, or darker red mixed in the stool as well. Bright red blood in the stools is known as hematochezia, and typically signifies bleeding in the rectum or the intestines. Older cats as well as younger cats can have hematochezia, and it is caused by a variety of factors. 

  • Constipation
  • Anal sacs and itchiness
  • Trauma
  • Infection
  • Cancer

Why Pooping Blood Occurs in Cats

Pooping blood is not always a sign of something serious; however, there is a chance that the diagnosis could be one that requires immediate treatment. Always make an appointment with your veterinarian if your cat is passing blood in the stool. 

Constipation

Constipation occurs when cats have trouble passing feces. The poop may be harder or another type of consistency and this may make it difficult to pass. Bowel movements can be infrequent or difficult to eliminate. Parasites, impaction, a foreign body, and certain illnesses like inflammatory bowel disease can cause constipation.

Anal sacs and itchiness

Anal sacs in cats are the anal glands in the rectal area. They can become impacted or abscessed and can cause bleeding in the stools.

Trauma

If a cat has been injured in the anal or rectal area, he may bleed when he goes to the litter box. Typically he will show signs of being injured. Polyps and injury due to a fistula or tear may cause your pet pain upon defecation.

Infection

If your cat has an infection in his colon or other part of his lower intestinal area of bowel, he may express pain when passing stool. An infection may cause internal bleeding that is present in the stools.

Cancer

If your cat has colon cancer or other type of intestinal cancer, he may have blood in his stools. Your cat may have other symptoms as well if he has cancer, such as weakness or loss of appetite.

What to do if your Cat is Pooping Blood

If you notice your cat has bloody stools, contact your veterinarian. Although this could be the result of something very minor, such as constipation or hardened stools, it still is a good idea to let a veterinarian check it out. Your vet may do blood and physical tests to determine the cause of your cat's bloody stool. He was also do a thorough examination of the rectum. He may also perform imaging techniques to take a more detailed look at the colon. 

A stool sample may need to be acquired by you before the veterinarian visit. He can also test this sample to gather more information as to the cause of the bloody stools. This may also show parasites. Also, the shade of the blood will show possibly where the bleeding is coming from – either from the rectum or the lower intestine.

Prevention of Pooping Blood

There may be ways to prevent your cat from experiencing this condition. Although some issues that may cause this health issue may not be able to be prevented, a lifelong healthy lifestyle can help. Regular veterinary visits can also diagnose conditions quite early, making them easier to treat with a better prognosis.

Watching and monitoring your cat’s grooming habits may also prevent blood in the stool. Extra fur in the digestive tract can cause this condition. Making sure your cat is on a proper diet with adequate amounts of fiber can help constipation, and preventing your cat from eating non-food items, such as pieces of toys, thread, or paper can also prevent this condition.

Making your sure your cat has plenty of water in their diet is another way to prevent constipation, which can cause blood in the stools. Stools that are hardened or look like little balls may be an indication that your cat may be having an issue. Always be sure to monitor your cat’s litter box usage so you can see if their stools look normal and verify that there is no blood within the feces.

Hello, So sorry to hear about your cat. If he is pooping blood, I would worry about parasites. Your vet can check a fecal sample and see what parasites your cat has. They can get you medication to help your cat feel much better. Good Luck.

Slimy Bloody Poop

My 2 month old kitten has been treated for worms specifically tape worms and before she was untreated I never found blood in her stool (she also has all her shots up to date and went in for her 2nd round of dewormer). She was pushing for a bit longer and when I cleaned her she had slimy blood on her anus. Im wondering if it is normal for her to do this after being treated with worms or if I should take her back to the vet with a stool sample.

Blood In Stool

I just checked my cat’s poop and there are bright red drops of blood in it. She is eating fine, acting normal, but the poop was firm. I don’t know if I should go to the vet immediately. I just lost my job so I am tight on funds but if you think it is necessary I will for sure go.

Red Patches In Stool

My cat hasn’t showed any signs of distress or pain in her daily life and she doesn’t make a fuss or anything when she poops (do cats make a noise or anything?) But I just noticed for the past 2-3 days that her poop is the usual softness and it looks like the usual medium brown but it had some patches of a sort of vibrant red color mixed in with it as well. I haven’t made any recent changes to her diet so I don’t know if I should be concerned about her digestive tract and if it’s healthy and working properly. I honestly can’t afford to take her to a vet right now so I wanted to get some input on what might be going on? But of course I’ll have to somehow manage to get her to see a vet if this persists.

Blood In Stool

For the past, I'd say 3-4 months I've been noticing a small amount of blood in my cat's poop. He is eight years old, just in case his age would help with anything. I haven't noticed any mood or behavior changes. He is still the same cuddly friendly cat. There hasn't been a diet change that I can pinpoint. Other than the fact that it's been cold and rainy, he hasn't been able to hunt and eat whatever the kill is. He won't poop in the litter box so it's easy to see when and how much blood is in his stool. It's not too much, but it's enough to concern me. It happens maybe once or twice every two weeks or one week. It will generally occur in one day or two days, not spread out. The poop is either just normal cat poop with the blood, or it's diarrhea. The blood is generally a normal red blood color, maybe a little bit darker. I'm just very worried about my cat.

My 17 year old cat, Gowlithe has had diarrhea for a large part of his adult/senior life. He only occasionally has normal ones. He has just started pooping in some strange place. In December it was the bathtubs. Now in any pile of laundry he can find. We've noticed blood now. What can we do outside of going to the vet. It's not something I can afford at the moment. I know my poor man is unhappy.

Bloody Poop

we have a 15 year old cat that has been loosing weight over the past year. he is extremely bony. But he eats like there is no tomorrow and drinks a lot of water. I took him to the vet last week and he did blood tests and said his kidneys an liver were in a bit distress. he also felt a mass in his stomach. he told me to feed him more protein and to give him some prescription food for the kidneys with his regular food. we came home tonight and found a large very bloody poop in the kitchen sink. it was very red like a large piece of liver. and smelled. What did he poop out - will he be ok tonight? I will take the bloody mess to the vet tomorrow. what should I be watching for. Please help.
