Switching my cat's food recently, and now she's having diarrhea. Could the change be the issue?

About three days ago, I switched my cat to a new food brand, and now she's having diarrhea, which has me feeling pretty worried. It’s been going on since yesterday, and I can tell she's not her usual energetic self. I’ve been really careful about not giving her any other treats or scraps, so I'm puzzled about the cause. I can’t help but wonder if the sudden change in her diet could be triggering this upset.

Answer

Yes, a sudden change in your cat's diet can definitely cause diarrhea. Dietary changes should always be done gradually to avoid upsetting a cat's digestive system.

  • Diarrhea that lasts for more than 24-48 hours
  • Lethargy or loss of energy
  • Lack of appetite or refusal to eat
  • Signs of dehydration (e.g., dry gums, sunken eyes)

Switching a cat's food can sometimes upset their gastrointestinal system—especially if it is done suddenly. This is why veterinarians typically recommend gradually mixing the new food with the existing one over about 7-10 days, allowing the cat’s system to adjust. Diarrhea can lead to dehydration and other complications, so it’s essential to monitor your cat’s condition closely. If the symptoms continue or worsen, it could indicate a more serious issue requiring veterinary attention.
