Diarrhea in cats
1. When the heart is heavy and we have worries
You discover loose stools in the litter box β and your heart races. "What's wrong with my kitty?" Perhaps she also seems quieter than usual, is eating less, or gives you a sad look that tells you something's wrong. As an owner, you're sensitive to every change in your pet. And you know: diarrhea can be a warning sign in cats β 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 β gently and naturally.
2. Diarrhea in cats β What is behind it?
Diarrhea (medically known as diarrhea) means that your cat is passing loose, mushy to watery stoolsβusually more frequently than usual. Diarrhea is not a disease, but a symptom. The body is trying to rid itself of something: bad bacteria, toxins, or food intolerance.
-
Acute diarrhea : lasts less than 14 days. There's usually a simple triggerβa change in diet, parasites, or stress.
-
Chronic diarrhea : Lasts longer than 2β3 weeks. This may indicate chronic inflammation, organ disease, or allergies. A precise diagnosis and treatment are important.
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 gut. Stress from visitors, moving, or new pets can also affect digestion.
3.2 Infections & Parasites
Bacteria, viruses, or parasites such as Giardia, coccidia, or worms are common triggers. Regular stool checks are especially advisable 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, 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 plasticβanything can become toxic. Prompt veterinary evaluation is essential.
4. Warning signs you should look 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 notice several of these signs, please see your veterinarian immediately. Better early than late, we believe.
5. First aid tips for at home
-
Fresh water : Always provide. Cats rarely drink much, but they need fluids when they have diarrhea. Chicken broth (without salt) can help.
-
Light food : Steamed chicken with some carrots or rice is easy to digest. Offer in small portions.
-
Rest & observation : Avoid stress, note behavior, measure temperature, describe stool (color, consistency).
-
Gentle intestinal helpers : psyllium husks, healing clay or zeolite .
