Why does cat diarrhea come back after finishing medication?
Prescription diets and temporary medications often fail to resolve chronic feline digestive issues long-term, causing severe diarrhea to return as soon as a treatment course ends. This leaves owners trapped in a stressful cycle of recurring symptoms, extra vet visits, and painful flare-ups like gas and liquid stools that standard foods cannot fix.
