Did you compare ingredients and nutritional content to see if there is something in the wet food that might be the culprit? Also, did you try adding water to the dry food to see if that makes a difference?Hi, I found your thread while searching for a similar issue with my kitten. Have you found a solution to the diarrhea with wet food? I tried giving wet food to my kitten three times already, and each time he ends up with soft stool/diarrhea after a few days. He is fine after going back to dry food...
There were other suggestions/ideas given to the OP that you might want to consider as well.
