Healthy cats: one has diarrhea & poops, other is picky. What to do?

If these cats have not been on long-term medication like probiotics and metronidazole, I would start these. Also, all cats might benefit from a food-allergy diet trial like Hills z/d fed exclusively for 8-10 weeks. This helps to rule out food allergies as a cause for chronic diarrhea. If these things don't work, you may have to actually send out fecal tests for culture and sensitivity to have done at an outside laboratory as most vet clinics are only equipped to do basic parasite fecal floats and smears in-house. Your female who is having behavior issues may benefit from anti-anxiety medications like Zylkene or Lorazepam, or even an anti-depressant. Since all three are young cats, it's most likely that they are sharing a parasitic or other intestinal infection that is causing chronic diarrhea, so I think you are on the right tract to continue to monitor for coccidiosis and giardiasis. They may need much longer-term treatment to clear these kinds of infection. Hope that helps!

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.

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 and a decrease in appetite could be a sign of a number of different problems. Intestinal parasites are possible, even for indoor cats, as are some infections or diseases like colitis or inflammatory bowel disease. If the diarrhea continues for more than 24 hours or seems to be getting worse, or if her appetite does not improve during that time I'd recommend seeing your veterinarian. They may treat her symptoms or recommend some testing like blood work or a fecal analysis depending on what they find during a physical examination.

I would recommend to try switching them to just a plain boiled chicken diet for a few days to see if this settles their stomach and add in some probiotics. I believe you can buy proviable paste online and give as directed. My concern though is that they may have a parasite or bacteria that they aren't finding in their fecal samples. If they aren't improving, contact your vet to see if you can either bring in just a fecal sample or deworm both of the prophylactically. I hope this helps!

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.

If you haven't already, a food trial on a different food that Yoda will eat (that isn't prescription) may help rule out any food allergies that could be triggering his symptoms (chicken, egg, and fish allergies are common in cats). Adding in a prescription probiotic supplement may also help with gut flora and firming up stools, and can be provided by your vet. If he didn't like the prescription food, trying a different version of it (IE the wet form instead of kibble) may also entice him to try it.
