My cat has bloody stool, mucus, and is vomiting. Is he constipated?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | unneutered | 10.2 lbs

Fassa hasn't been feeling well , he has bright red blood and mucus in his stool and just going a little bit at a time like maybe a quarter size spot (also not always going in his box) and is vomiting on and off. He is still eating and drinking and it doesn't seem to be consistent . He was good yesterday but the day before and today it's happening. Nothing has changed (same food , litter , ect ) he isn't acting any different or acting lathargic ... Is this something we should be worried about ?

I would be worried about constipation. If he is having trouble passing stool they will get blood and mucus. They will also vomit when they are constipated. He may need an enema to help remove the feces. They may be able to feel his belly and see if they feel hard stool present or they may want to take xrays. Try and encourage as much water as possible and if he will eat canned food try that. The high moisture content can help. IF it continues they will want to see him and give an enema and possibly put him on a stool softener.

    If this has been happening for six months and is occasional, then I don't think he needs to see a vet more urgently at this time. The straining to defecate could be from hard, dry feces, worms, or other abnormality within the rectum. You may consider getting him some stool softeners (can get this at the pet store), or adding more water to his food if the stool appears too hard and dry. Below is a link to a fecal score guide. This will help you determine if there is a problem with the feces. I hope that helps and Atticus gets better soon.

Hi, thanks for using Boop by Petco! Poor Mickey! I would contact your vet for more medication and change Mickey's diet. Constipation is a symptom of something else not a primary disease. In a 5 month old cat it is likely dietary but there can have motility issues that are genetic with their colon. Be sure he has been dewormed appropriately and is vaccinated. Increase water intake by feeding a canned food diet and slowly adding water. There are also prescription diets available (royal canin gastro-intestinal until 1 year of age then fiber response). I wish you the best

My cat is having trouble passing a turd... He keeps producing small amounts of this brown mucous on the pee pad I have in front of the litter box, but hasn't been able to completely eliminate the actual piece. He's eating normally & drinking plenty
Seeing your vet ASAP is definitely a good idea to make sure there isn't an impaction causing the severe constipation that may need an enema or stool softeners to resolve. In the meantime, you can try offering a little bland yogurt to try and help the soften the stool, as well as make sure he's drinking plenty of water by mixing some into his food, but if Booboo is in severe distress, hasn't passed any stool at all, or is having other symptoms such as abdominal pain or stops eating, you should seek out veterinary care from your vet or a local ER clinic immediately.

My cat with a dislocated hip has been constipated for a few days. Today he finally pooped but it was very bloody and it seemed as if his rectum was bleeding badly. Should I be concerned?
Hi, thanks for using Boop by Petco! Poor Co! Stool that is hard and sits in the colon for a while can have blood on it. If it was hard then you should contact your Vet to discuss medications to help soften the stool. If the stool was diarrhea then he may need antibiotics. If the blood persists get in touch with your Vet. I hope this helps!

My cat is constpated. Stool right there but straining without results. Vomited twice from straining. Had good BM yesterday. Gave oil goo from pet store.
Poor Eddie! Before doing anything else, make sure that Eddie is urinating normal volumes in the litter box without straining. Urinary obstructions in male cats can easily be mistaken for constipation because these cats will strain in the litter box, go in and out of the litter box, vomit, and sometimes vocalize. It is extremely important to assure that he is urinating normally without straining because urinary obstructions are a life-threatening situation that require emergency veterinary attention. If Eddie is urinating appropriately and does not have a bowel movement at home tonight, you should take him to the vet in the morning. The vet will be able to examine him and may need to take abdominal x-rays to determine the degree of constipation or stool impaction. Based upon those results, the vet may need to perform an enema or provide Eddie with prescription-based stool softeners. I hope this helps and that all goes well!

My cat has been constipated for about a week and a half now. He is eating very little, not drinking much water, and is lethargic. I've tried adding coconut oil and water to his food, but it isn't helping much. I know he's dehydrated because he only e
I would advise to bring him in to a veterinarian ASAP. I would highly advise against waiting 4 days. It does indeed sound like your cat is constipated, and there may be some underlying health issues that worsen the condition such as kidney disease. In severe cases of dehydration, cats can become fully obstructed. As you can imagine, this can be very dangerous. In mild cases of constipation, subcutaneous fluids and a laxative can aid in recovery. In more severe cases, IV fluids, and sedation with manual extraction are required. Due to the recent onset of vomiting, it appears your cat's constipation is progressing, and needs medical intervention.

Peanut has been having diarrhea and continuous vomiting for more than a week. The vet at first said he had gastral infection. We gave meds. It kept going. We did 5 blood tests, x ray, and other examinations. And 2 days ago blood started dripping out
There are many things that could cause his symptoms. Unfortunately they are non-specific and could be a symptoms of almost anything. Bleeding from the anus frequently signifies a serious disorder. Possible causes of bleeding from the anus can include polyps or tumors of the colon or anus, abscess or infection of the anal gland, constipation, blood clotting disorders, autoimmune disease or even certain types of poisoning. Any chance he ate a toxic plant or was exposed to any toxins? Intestinal parasites are another possibility. Whipworms are intestinal parasites. They are about 1/4-inch long and live in the cecum and colon of the cat, where they cause severe irritation to the lining of those organs. This results in watery, bloody diarrhea. They can also have weight loss and general debilitation. Whipworms are one of the most pathogenic (harmful) worms found in cats. Has a fecal sample been tested? Whipworms can also cause vomiting. Any chance the blood is dripping from his penis and

It is possible that this particular stool was difficult to pass and you helping to remove it may have caused a small amount of bleeding from the rectal tissue. Cats can become constipated, and if she has been passing less stool than usual, straining to defecate and had a decreased appetite I would recommend seeing a veterinarian. There are some other things that can cause blood in the stool as well including intestinal parasites, colitis or even inflammatory bowel disease. If the blood is persistent you should make an appointment to see your veterinarian as well.

If he is still vomiting then he needs to be examined by a vet for treatment. If he is constipated, he may need an enema and medication to help soften his stool. He might also need an anti-vomiting medication.

Cat is spitting up white foam substance and is squatting trying to have a bowel movement.Meowing as if in pain.
Your cat could be severely constipated and the straining can make him nauseous. For severe constipation, your pet should be seen by a vet. Hard stool building up in the colon stretches it out of shape, and it also causes stretching of the muscles around the anus, causing perianal hernias that trap the collected feces, effectively making a plug. Your pet may need more than one enema and even manual extraction of the feces in order to relieve this episode. To help avoid this in the future, you can add Miralax to the food. Miralax is a very gentle, easy to give treatment for constipation, available over the counter at any pharmacy. The dose of Miralax is 1 tsp per 50 lbs mixed in with food once a day. You can also add a tablespoon of vegetable or olive oil to his food once daily, or add a couple of teaspoons of canned pumpkin (not pie filling) to his food daily.

I've been feeding my cat 9lives cat food, before I knew a lot of people had issues with that brand. Well now my cat has been throwing up, and blood in his stool.
Poor Sebastian! While this vomiting could be caused by his food, if he's been on it a while, then it's more likely caused by something else. Vomiting and blood in the stool can be caused by a severe GI illness, a foreign body, severe intestinal parasite infection, GI ulcers, or exposure to toxins. Because blood in the stool is not normal and can be caused by serious illness, it would be best that he is taken into a vet now for an exam. The vet can diagnose what is causing the vomiting and bloody stool, and can treat him for it.
