Poor guy. He sounds ill indeed. Many disease processes can cause loose bloody stool including: intestinal parasites, pancreatitis, inflammatory bowel disease, lymphoma (cancer of the intestines), dietary indiscretion (eating something he shouldn't have), and even a bacterial infection. The first step would be to do a full panel bloodwork analysis, fecal exam and urinalysis done on Oliver. This should be ble to narrow things down quite a bit so that your vet can know what Oliver needs treatment wise. I would suggest scheduling an appt for him soon at your local vet. I hope that your pet Oliver is able to recover from his bloody stool and illness. Best wishes and take care.

Thank you for submitting your question regarding Jade. I am sorry to hear about the issues she is having and that her veterinarian wasn't as helpful as you hoped. I would recommend seeking a second opinion for her with another veterinarian. Unfortunately, there is likely a disease causing her issues. Pancreatitis, inflammatory bowel disease and intestinal cancer are common in cats with gastrointestinal signs. Blood work and an abdominal ultrasound are generally necessary to reach a diagnosis. Depending on these results, treatment can be started. A prescription diet is many times needed. I generally use a hydrolyzed formula as this will have anti-inflammatory properties for the gut. A probiotic can also help. B12 injections are needed when there is a cobalamin deficiency. In some cases, steroids are necessary. I hope this information helps!

Thanks for using Petco Pet Education Center, formerly Petcoach! Vomiting and bloody stools can be observed with many conditions such as gastroenteritis, dietary indiscretion, kidney disease, pancreatitis, among many other possibilities. I recommend that you have Mittens evaluated by your veterinarian for further assessment and treatment. They would be able to check for these possibilities and others depending on the findings on exam. Treatment would be based on findings. Good luck and have a great day! Hoping for a speedy recovery!

She could have food allergies, inflammatory bowel disease, pancreatitis, hyperthyroidism, infection, or liver/kidney disease. It would be a good idea for your vet to run some bloodwork, including a complete blood count, chemistry profile, urinalysis, and thyroid level to screen for these diseases. If the diagnostic tests are normal than you could try her on a hypoallergenic diet (like z/d or d/d) and add a probiotic to her diet to see if that helps. Your vet could also try Metronidazole to see if that helps the problem, too. Hope she starts feeling better soon.

My kitten has bloody stool and looks inflamed. What should I do?

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.

My cat is throwing up and has blood in his stool. What should I do?

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.

Why is my cat vomiting, has diarrhea, and bloody stool but is active?

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.

Why is my cat straining to poop, losing weight, and eating more?

Ollie needs to be examined by his veterinarian for a few conditions including hyperthyroidism, hypertension, intestinal parasites and Felv/FIV. It sounds like he is very sick and I recommend to have him examined within the next 24 hours. Getting the correct diagnosis and starting treatment quickly tend to give pets the best prognosis. I hope this helps.

My 11-year-old cat has blood in her stool after pooping. What's wrong?

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.

Why is my cat vomiting, not eating, straining, and has bloody poop?

This is a medical emergency, and Lucky needs to see a vet immediately. He could be suffering from a foreign body, GI polyps, or GI tumors causing him to vomiting, not be able to poop, and not eat or drink. He needs veterinary treatment now. I would see if there is an ER vet clinic in your area. If there isn't, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website. Please take him into a vet immediately.

My cat is vomiting and has blood in its poop. What could be wrong?

Hello. Vomiting and blood in the feaces could be signs of a mild gastritis, or could be much more severe. If the poop was very big and hard, then the vomiting could be secondary to Wally being constipated. If the poop was soft and liquid then he could have a gastritis. If he is eating/drinking well, and just had one episode and is back to normal, you can monitor him for now, but if he is lethargic, still vomiting, and if the blood gets worse or continues, then I would bring him to a vet. Good luck with Wally.
