Cats will not die if they don’t over-excess the old food. If they don’t over-excess the old food, you can put some probiotics in the new food to help the cat change, or eat smaller meals more often and soak them until soft to help the cat’s gastrointestinal function. Adaptation, generally the cat’s stomach will adapt within a few days.

Tip:

If changing food causes cats to have frequent diarrhea, parents should stop changing food as soon as possible and use the original food.
