Learn how to identify the cause of your cat's diarrhea, when to try a gastrointestinal diet, and when to see a vet. Practical advice with Calibra options.
Quick answer
For mild, uncomplicated diarrhea in an otherwise healthy adult cat, start with a bland, easily digestible diet like Calibra Cat Life Pouch Sterilised Duck. If diarrhea persists beyond 24-48 hours or is accompanied by blood, vomiting, or lethargy, stop home management and consult your veterinarian immediately.
Identifying the cause of your cat's diarrhea
Diarrhea in cats is a symptom, not a disease. Common triggers include sudden diet changes, food intolerances, stress, parasites, or infections. Before changing food, note how long the diarrhea has lasted, whether your cat is still eating and drinking, and if there are other signs like vomiting or fever.
If your cat has been recently neutered or spayed, hormonal shifts can sometimes cause temporary digestive upset. In that case, a food designed for sterilised cats, such as Calibra Cat Life Pouch Sterilised Duck, may help stabilize digestion while supporting overall health.
Choosing the right food for an upset stomach
For a cat with a sensitive stomach, look for a diet with a single, high-quality protein source and minimal fillers. Calibra Cat Life Pouch Sterilised Duck is grain-free and made with duck fillets in sauce, offering high meat content and taurine for heart and eye health. This can be a gentle option for adult cats with mild digestive upset.
If your cat has a diagnosed gastrointestinal condition, a veterinary diet may be more appropriate. Calibra's Prescription Diets range includes options like the Calibra VD Dog Crunchy Snack Gastrointestinal, which is designed to support digestive function alongside a Veterinary Diet. Always follow your vet's guidance for prescription diets.
How to transition to a new food
When switching your cat's food, do it gradually over 7-10 days to avoid worsening diarrhea. Start with 25% new food mixed with 75% old food, then slowly increase the proportion. For wet food pouches, you can also add a little warm water to encourage hydration.
Monitor your cat's stool consistency daily. If diarrhea improves, continue the transition. If it worsens or new symptoms appear, stop and consult your vet. Remember that some cats need a longer transition period, so be patient and observe closely.
When to act: a simple diagnosis guide
- Symptom: Soft or loose stools for less than 24 hours, no other signs of illness, cat is eating and playful. This is often a mild upset. Try a bland diet like Calibra Cat Life Pouch Sterilised Duck.
- Likely cause: Sudden diet change, stress, or eating something unusual. Often resolves on its own. Keep your cat hydrated and monitor stool quality for 24-48 hours.
- Corrective action: Switch gradually to a gentle, grain-free food. Offer small, frequent meals and fresh water. If diarrhea stops, continue the new diet. If not, see a vet.
- Stop and see a vet: Blood in stool, vomiting, lethargy, loss of appetite, or diarrhea lasting more than 48 hours. Do not delay professional care. Home management is not enough.
