Why is my cat's rectum red with pus and bloody diarrhea?

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 not the anus? In younger cats a common cause of bloody urine is the presence of crystals in urine (crystalluria). When left undiagnosed and untreated, these crystals can lead to blockage of the urethra in some male cats. Has a urinalysis been done? This is the best I can tell you at this time. If you have more detailed questions or want to speak one on one you can also opt to do a private consultation with me. Hope this helps. Best wishes.

It looks like Coco may have a small amount of rectal tissue prolapsed. This can occur if they have parasites, chronic diarrhea, foreign body or constipation. I recommend having her checked for intestinal parasites and possibly adding water to her food to help her pass stool more easily. If she is vomiting or showing any other signs of illness she should see a pet ASAP.

Small specks of red blood during a bout of diarrhea is not unusual as the delicate lining of the back passage can become damaged from straining. As long as he is bright and alert, eating and drinking it would be ok to leave him but if any lethargy, weakness or vomiting occurs he should be seen urgently by your vet. Be sure he is up to date with deworming medication as intestinal worms are a common cause of diarrhea in young kittens

Garfield seems to be suffering from a severe gastrointestinal condition, i do not recommend to stop feeding him, this can do more harm than good in cats, you need to take him to the vet as soon as you can in order to get treated, he will probably need an antibiotic course , a special prescription food and some meds to stop the diarrhea.

It sounds as Jasper is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking him to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.

It is very possible the blood is from the irritated colon. The colon gets irritated secondary to the diarrhea. You can try an over the counter probiotic to help good bacteria return to the colon and help stop the diarrhea. If the diarrhea does not resolve he needs to see a vet for possible stronger medications.

It looks like Ollie might be having a partial rectal prolapse, which can happen with diarrhea from things like parasites or from constipation. The blood might be related to diarrhea or if it's a small amount it could be from the rectum and from irritation. I would recommend seeing a veterinarian right away given his age - if it is a small prolapse it could get worse quickly and require surgical repair. The vet can hopefully determine the underlying cause and offer treatment.
