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.

It would be best to have Joe seen right away by a veterinarian if he is urinating and defecating blood - that might become a very serious problem, quickly, and getting him treated early will be best for him.

I have a cat named Nimbus, he's a persian and he's 4 months old... I just noticed that his poop is yellow and soft, his poop have little blood specs on it and has a pretty bad smell... I don't know what's going on because he's still playful but after that he lays down or sleep... He also pooped black and yellow... I think it is serious but I still need advice from professional veterinarian. We can't get him to vet because of the outbreak. What can I do about it?

Diarrhea
Blood In Stool

My cat Izzy has recently began to poop blood. It's usually diarrhea that's a bit slimy looking with either a lot of blood or a little smear of blood. She doesn't act any differently and is still active with zero change in her eating or drinking habits. I've taken her to a vet and had a smear done on her stool, but everything came back as negative. I just came back from visiting family and noticed there is a lot of blood in her litter box and it's dark, but it could be because it's been sitting for awhile. Just was wondering if anyone else had my experiences or if anyone had any advice? I will of course call my vet soon and ask for their opinion, but until then, suggestions, advice or opinions would be very helpful.

My kitten who is 4 months is having runny bowel movements with blood in with it. My family says that it could be worms but I want to have an overview of what it could possibly be. He uses the litter box well and drinks a good amount of water with a good amount of food as well.
