Why is my cat having diarrhea and going to the litter box often?

I am sorry to hear about your kitty! If the food appears different than the one he normally eats it is possible that perhaps there is a different additive or food coloring that has upset his stomach (or is it possible it is a different flavor even though the brand is the same). We can see some pets have GI upset from quick changes in diet. That being said, we can also see diarrhea from other causes, including GI parasites, bacterial overgrowth, inflammatory bowel disease, as a symptom of systemic illness, and more. If he is still energetic with no vomiting you could try getting a probiotic from your vet or the pet store for him which can sometimes help with diarrhea and feeding something bland for a few days (such as plain white rice and shredded boiled chicken or lean ground chicken) or picking up the food you normally get at the pet store and trying this for a few days. If he is having urgency so often he isn't making it to the litterbox, however, it is quite possible he has colitis http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=677 and will likely need prescription medication to get the diarrhea under control, so the fastest solution to eliminating the problem is to have your vet examine him!

Diarrhea can occur with a food sensitivity or allergy, so her current diet could be contributing to the problem. Other possibilities include persistent parasites, bacterial imbalance, or inflammatory bowel disease. You may want to consider putting her on a prescription gastrointestinal or hypoallergenic diet. A probiotic supplement may help. Lastly you may want to consider bringing her back to the vet to have a fecal test done if this hasn't been repeated. It may be that she needs a course of anti-diarrheal medication in order to fully resolve the diarrhea.

I would recommend that Pussy be checked out by a vet as soon as possible. Her symptoms could be caused by intestinal parasites (worms, coccidia, giardia), bacterial or viral infection (panleukopenia), IBD, intestinal lymphoma, food allergies, among a few others. From the picture, I am also concerned that she may have a prolapsed rectum. This can occur with straining during diarrhea. Sometimes this prolapse will require surgery to put it back in place and allow it the chance to heal. A vet may recommend intestinal parasite screening or viral testing to determine the cause of her illness and prescribe appropriate treatment. Unfortunately, without physically examining Pussy, it is illegal for us to make any specific medication recommendations.

Poor Lily! Diarrhea even in old cats isn't normal. I have diagnosed parasites especially giardia in cats who are strictly indoors. You could try a sensitive stomach food and some probiotics to see if this helps. If not, I would strongly recommend your vet to take a look at her. Your vet will likely do a fecal and possibly blood work, thyroid test and x-rays. I would also make sure they rule out giardia and campylobacter. In older cats, I worry especially worry about inflammatory bowel disease and GI cancer. If your vet is concerned about this, they will be able to talk to you about potential diagnostics (Ultrasound and GI panel, etc) and treatments to help her feel better. I hope this helps and she starts to feel better soon!

Submit a stool sample to your veterinarian to diagnose intestinal parasites or bacterial overgrowth. Deworm him if indicated. You can also have the vet collect a sterile urine sample to submit for urinalysis and culture to rule out UTI or stones. In the meantime, try a 24 hour fast followed by a bland diet in small, frequent amounts. Begin with one tablespoon of food every hour and gradually increase the amount. Feed bland until the stool is normal then transition slowly to the regular diet. Consider a veterinary probiotic, such as FortiFlora, ProViable or ProStora, to promote gut health. A pheromone product such as Feliway spray or plug in diffuser may decrease any anxiety. A small animal repellant along the border of your property will keep strange animals away and out of sight. Thoroughly clean soiled areas using an enzymatic cleaner such as Nature's Miracle.

Common causes of diarrhea or loose stools in a young cat include food intolerance, food allergies, intestinal parasites, bacterial or viral gastroenteritis, stress colitis, among a few others. Based on her history, stress from the visit or a change in treats may be the cause. You can try a medication like ProPectalin AntiDiarrheal Gel for Dogs & Cats that has probiotics and a small amount of kao pectate in it - it also tastes good. If the diarrhea/soft stools continue next week, or if Pico starts showing signs of lethargy, inappetence, or straining, I would definitely have her checked out by a vet.

It's possible the cat having diarrhea is having some sort of food allergy, or it could be stress related. Changing the diet or attempting a food trial with your veterinarian may help rule out any potential allergies and help relieve the diarrhea if there were no parasites or illness present. Reducing stress may also help, and adding in a pheromone diffuser in shared rooms can help with reducing stress along with making sure each cat has their own access to the litter box, food, water, etc without competition (that could lead to stress or accidents outside the litter box). As for your picky eater, switching foods may also encourage them to try a little more.
