Switching your cat’s food can be tricky and requires some time. A sudden change may upset their stomach and cause diarrhoea, which is unpleasant for both of you.

However, with careful planning and a gradual transition, you can make the switch smoothly.

This guide explains the causes of diarrhoea in cats and how to ensure a safe, gradual food transition.

1. Why Do Cats Get Diarrhoea When Their Food Changes?

Cats have sensitive digestive systems. A sudden change in diet can disrupt the balance of their gut flora, leading to digestive issues like diarrhoea and vomiting.

Diets that can trigger diarrhoea in cats include raw food, BARF diets, or high-fibre options. Even switching between dry and wet food can upset their stomach. Additionally, some cats are sensitive to cow’s milk, which may also cause digestive issues. 

a) Ingredients To Avoid During Transition

Certain ingredients can be harmful to your cat’s digestive system, especially during a diet change. Avoid foods containing:

  • Artificial Preservatives: Ingredients like BHA and BHT can disrupt gut microbiota and cause inflammation, leading to gastrointestinal upset and diarrhoea.
  • Fillers: Corn, soy, and wheat are hard for cats to digest, as they lack the enzymes to break down these plant-based ingredients, resulting in stomach upset and diarrhoea.
  • Artificial Colours and Flavours: These additives can irritate the digestive tract and trigger allergies or sensitivities, contributing to digestive issues like diarrhoea.

 

2. How To Safely Change Your Cat's Food?

If you are thinking of changing your cat's food, you have to do this slowly and safely.

Follow these steps to ensure a smooth transition:

a) Start Slowly

  • Begin by mixing a small amount of the new food with your cat’s current food.
  • A good starting ratio is 25% new food and 75% old food.

b) Gradually Increase the New Food

  • Over the course of 7-10 days, gradually increase the proportion of the new food while decreasing the old food.
  • A typical schedule might look like this:
          - Days 1-3: 25% new food, 75% old food
          - Days 4-6: 50% new food, 50% old food
          - Days 7-9: 75% new food, 25% old food
          - Day 10: 100% new food

    c) Monitor Your Cat’s Response

    • Keep an eye on your cat’s stool consistency and overall behaviour during the transition.
    • If you notice any signs of digestive upset, slow down the transition process.

    Extra Tips

    a) Smaller, More Frequent Meals:

    • Instead of two large meals a day, try feeding your cat smaller portions more frequently.
    • This can help their digestive system process the new food more easily.

    b) Ensure They Have Plenty Of Fluid:

    • Ensure your cat has access to fresh water at all times.
    • Proper hydration helps keep their digestive system functioning smoothly and can mitigate the effects of a diet change.

      c) Consistency Is Key:

      • Stick to the same feeding area and schedule that your cat is used to.
      • Cats are creatures of habit, and maintaining a consistent routine can help reduce stress during the transition.

      d) Try Digestive Support:

      • Consider adding probiotics or digestive enzymes to your cat’s food during the transition period.
      • These supplements can help support your cat’s gut health and make the transition smoother.

       

      3. What To Do If Your Cat Is Still Having Diarrhoea?

      Most cats adjust well to a new diet when changed gradually. However, if your cat has diarrhoea and shows any of these signs, there might be a health issue:

      • Not eating or drinking
      • Vomiting
      • Lethargy
      • Watery diarrhoea
      • Frequent diarrhoea
      • Blood in the diarrhoea

      Cats can get diarrhoea from worms, toxins, or stress. If you're worried about your cat, schedule a vet appointment right away for a check-up. They can provide guidance and may recommend a different diet or additional treatments.

        4. Takeaway (TLDR)

        Cats can experience diarrhoea when their diet changes due to their sensitive digestive systems, with triggers including certain food types and harmful ingredients like artificial preservatives, fillers, and additives.

        To safely change your cat's food, gradually mix in the new food over 7-10 days while monitoring their response, and consider smaller meals, consistent routines, hydration, and digestive aids for a smoother transition.

        If your cat continues to have diarrhoea despite a gradual diet change and shows signs like not eating, vomiting, lethargy, or blood in the stool, it may indicate a health issue; consult a vet for guidance and potential treatment options.
