Two of my cats suddenly have diarrhea after I changed their food, should I switch back?

I recently changed my cats’ food, and now two of them have started having diarrhea. This only began after the switch, so I’m wondering if the new food might not be agreeing with them. Should I go back to their old diet, or is it normal for cats to have this kind of reaction temporarily when switching foods?

Answer

It sounds like the recent change in your cats’ diet might be causing them some digestive issues. Diarrhea can occur when switching foods, but it’s important to monitor their health closely.

  • Sudden dietary changes can lead to digestive upset in cats.
  • Gradual transition to new food is often recommended to avoid issues.
  • If symptoms persist, switching back to the old diet may be necessary.

When changing a cat’s diet, it’s common for some to experience diarrhea as their digestive system adjusts. Ideally, any food transition should be done gradually, mixing increasing amounts of new food with the old over a week. If your cats’ symptoms continue beyond a few days or worsen, going back to their previous diet might be a wise first step while consulting with a veterinarian for further advice.

If this is an emergency, please seek immediate veterinary care.
