Is it Normal for a Cat to Have Diarrhea?
No, it is not normal for cats to have diarrhea. However, if your cat has diarrhea but seems fine, the issue might be minor and transient.
Cat diarrhea can result from an array of gastrointestinal problems like food allergies or bacterial infections and should be taken seriously. The good news is that if your cat has diarrhea but seems fine, the underlying cause is likely benign.
Why Does My Cat Have Diarrhea But Acts Fine?
There are several reasons your otherwise healthy cat has diarrhea but seems fine. Here are some of the most common causes:
- Diet Changes. One of the common causes of diarrhea is a sudden dietary change, especially in cats with sensitive stomachs. For example, giving wet food to a cat used to eating only dry food will result in diarrhea. When switching your cat’s old food, make the introduction of the new food slow and gradual.
- Food Allergies. Cats can be allergic or intolerant to certain foods. In such cases, they will show signs of gastrointestinal upset (usually diarrhea but sometimes also vomiting). When suffering from food intolerances and allergies, a cat will seem otherwise fine.
- Imbalanced Gut Biome. If the good bacteria in the cat’s gut are inhibited in some way, it can cause indigestion and changes in the feces consistency. For example, gut biome imbalances can occur after prolonged use of antibiotics. Introducing probiotics can help resolve this issue and normalize bowel movements.
- Lack of Fiber. Fiber is an undigestible but necessary nutrient for a healthy digestive system. Low fiber diets can result in loose stools and can be fixed by adding high-fiber foods to the cat’s diet or using prebiotic supplements. If your cat has diarrhea but seems fine, it may need more prebiotics in its diet.
Can Cats Have Diarrhea for No Reason?
No, healthy adult cats should not have diarrhea for no reason.
While some diarrhea bouts are benign and self-limiting, others can be the result of severe or even life-threatening conditions.
For example, acute diarrhea in cats can be caused by bacterial infections, viral infections, intestinal parasites, foreign objects, or ingestion of toxins (foods, plants, chemicals, human medication).
Chronic diarrhea in cats can be caused by kidney disease, thyroid gland issues, pancreatitis, or IBD (inflammatory bowel disease).
When your cat has a loose poo, consider the overall situation. If your cat has diarrhea but seems fine, monitor it and use over-the-counter supplements or home remedies. However, if, in addition to diarrhea, it is showing other signs and symptoms, seek veterinary care.
Does Cat Diarrhea Resolve on its Own?
Yes, diarrhea can resolve on its own, especially if your cat has diarrhea but seems fine and does not show additional signs and symptoms.
For example, if the diarrhea was caused by new food and sudden dietary change, it can resolve on its own once the stomach gets used to the new cat food.
However, if you notice your cat’s poop is black or bloody, it is time to get them to see a DVM. This is a sign of something more serious, with possible causes ranging from intestinal parasites (like roundworms and hookworms) to viral infections.

Can Cat Diarrhea Spread to Other Cats?
No, diarrhea itself cannot spread to other cats.
However, some infectious causes of diarrhea (such as the parasite Giardia, bacteria Salmonella, or the feline leukemia virus) can spread to other cats. They spread via food/water bowls or the litter box if contaminated with fecal matter. If your cat has diarrhea but seems fine, chances are the underlying cause cannot be transmitted to other cats.
How Long Does Diarrhea Last in Cats?
It depends on the underlying cause. Cat diarrhea can last anywhere from a couple of hours to several days or even weeks.
However, if your cat exhibits symptoms for more than 1 to 2 days or your cat’s stool is discolored, it is important to seek veterinary help. These can be signs of life-threatening underlying causes.
When Should I Be Concerned About My Cats Diarrhea?
You should be concerned when your cat’s diarrhea is discolored, tarry, mucousy, bloody, or lasts more than a day or two.
You should also be worried if your cat is showing additional worrisome signs such as lethargy, loss of appetite, vomiting, or weight loss. In such cases, you need to get proactive and see a vet.
The vet will perform a physical examination and order diagnostic tests (stool sample analysis, blood work, abdominal x-rays, ultrasound) to determine the underlying cause.
The good news is, in general, you should not be worried if your cat has diarrhea but seems fine.
