Diarrhea in cats
1. When the heart is heavy and we have worries
You discover runny stool in the litter box – and your heart races. "What's wrong with my cat?" Perhaps she also seems quieter than usual, is eating less, or is showing you with a sad look: something's not right. As a pet owner, you're sensitive to any changes in your animal. And you know: diarrhea can be a warning sign in cats – sometimes harmless, sometimes serious. That's why it's important to know what causes it, what to look out for, and how you can help your cat – gently and naturally.
2. Diarrhea in cats – What's behind it?
Diarrhea (medically: diarrhea) means that your cat is passing unformed, loose, or watery stools – usually more frequently than usual. Diarrhea itself is not a disease, but a symptom. The body is trying to rid itself of something: harmful bacteria, toxins, or food that it cannot tolerate.
-
Acute diarrhea : lasts less than 14 days. It is usually caused by a simple trigger – a change in diet, parasites, or stress.
-
Chronic diarrhea : if it lasts longer than 2–3 weeks, it could be due to chronic inflammation, organ disease, or an allergy. A thorough diagnosis and investigation are important in these cases.
3. Causes at a glance
3.1 Harmless trigger
Not every case of diarrhea is cause for panic. Sometimes a new snack or a change in feeding routine is enough to upset a cat's sensitive digestive system. Stress from visitors, moving house, or new pets can also affect digestion.
3.2 Infections & Parasites
Bacteria, viruses, or parasites such as Giardia, coccidia, or worms are common causes. Regular stool checks are particularly important for outdoor cats. Some infections are mild, while others can severely strain the immune system.
3.3 More chronic diseases
If diarrhea recurs or persists, you should consider chronic causes: IBD (inflammatory bowel disease), colitis, liver or kidney disease, or hormonal disorders such as an overactive thyroid.
3.4 Foreign substances & toxins
Cats explore with their mouths and paws. Whether it's cleaning product residue, medication, plants, or plastic – anything can become toxic. A prompt veterinary examination is crucial.
4. Warning signs to watch out for
In addition to soft stools, the following accompanying symptoms should be taken seriously:
-
Blood or mucus in the stool
-
Frequent vomiting, loss of appetite, fever
-
Dehydration (dry skin, sunken eyes)
-
Apathy or restlessness
If you observe several of these signs, please go to the vet immediately. Better safe than sorry. That's our opinion.
5. First aid tips for home
-
Fresh water : Always provide it. Cats rarely drink much – but they need fluids when they have diarrhea. Chicken broth (without salt) can help.
-
Bland diet : Steamed chicken with a little carrot or rice is easily digestible. Offer in small portions.
-
Rest & observation : Avoid stress, note behavior, measure temperature, describe stool (color, consistency).
-
Gentle intestinal aids : psyllium husks, healing clay or zeolite .

📋 Tip for your everyday life
Keep a little diary of your cat's bowel movements: What does your cat eat, how often does she defecate, what does it look like? This will help you – and your vet – enormously if there are any follow-up questions. And it will give you the feeling: I'm keeping an eye on this and it's being lovingly observed by me.
