How to improve soft stool or diarrhea

1. Switch food

Soft stool, diarrhea, or smell means current food unfit—switch.

Food advice: high-protein chicken or fish, grain formula, probiotics added, easy to digest for sensitive guts; clear, traceable ingredients.

2. Switch the litter box

Open boxes let odor escape.

Box advice: a fully closed box hides odor and reduces tracking.

3. Switch litter

Litter advice: tofu or mixed litter, high absorption, good odor control.

4. Adjust diet

Don’t feed only dry food; too many treat cans are bad. Occasionally boil meat or egg for vitamins and fiber.

Improve gut function

For frequent soft stool, keep probiotics at home.

5. Regular deworming

Deworming matters; monthly in summer.

6. Clean the litter box timely

Clean daily, change litter regularly.
