Can changing my cat’s diet suddenly cause harm? - Haines Road Animal Hospital
Yes, they can, just because they get so used to eating one certain diet. I would recommend that we slowly transition the diet over one to two weeks, just to prevent any gastrointestinal upset, such as vomiting and diarrhea.

Yes, typically very transient and mild harm, but yes. The most common thing we see is when a diet has changed abruptly is gastrointestinal signs. What does that look like? Some cats can vomit, but more often they'll have diarrhea. So if you do have to make a change, or if you're planning on making a change, just do it gradually over the course of maybe a week. Use this period to gradually mix the new food in slowly, giving more and more of the new food to make sure that they tolerate it.

Switching your cat's diet abruptly could potentially cause gastrointestinal upset, such as vomiting or diarrhea. However, cats are generally more tolerant than dogs when it comes to changing their food. It's not uncommon for pet owners to feed their cats different types of canned food with various proteins, which cats can usually tolerate well.
