Hi there. Thank you for using Petco Pet Education Center, formerly Petcoach. So sorry that Smudge is having this issue. Any abrupt changes in diet can cause diarrhea. Do you just feed it to her once in a while? If you feed it everyday her intestinal system may eventually get used to it. My guess is that there is an ingredient in the food that is causing some intestinal upset for Smudge. What that is, we will likely never know. If you try a few different canned cat foods you may eventually find one that agrees with her. If you get a canned food that is the same brand/flavor as her dry food you probably would have a greater chance of success. Hope this helps. Best wishes.
